Audio-Technica Intro New Open Ear Audiophile Headphones

Leave a comment

STOW, OH, October, 2024 — Our friends at Audio-Technica are at it again and have just announced the introduction of their ATH-ADX3000 Open-Air Dynamic Headphones, designed to bring true high-end sound quality to the under-$1,000 usd headphones category. Celebrating 50 years of headphone design and production, the new ATH-ADX3000 features Audio-Technica’s most advanced driver technology to deliver natural, spacious audio.

A Few Takeaways (more below)

Light and comfortable, weighing less than 10 ounces and with velour earpads, the ATH-ADX3000 headphones are comfortable, to say the least. If you are a home recordist know that they’re ideal for long mix sessions, and not just due to comfort or their open-back design.

58-millimeter integrated driver units house tungsten-coated diaphragms (which produce excellent transient response), voice coils, baffles, and pure iron magnetic circuits. Coupled with Audio-Technica’s proprietary Core Mount Technology that optimally places the driver units, this results in full-range audio reproduction across an astonishing 5Hz–45kHz frequency response that needs to be heard to be believed.

These near-flagship headphones come with a specially designed aluminum carrying case.

Uses the A2DC proprietary coaxial connector which reduces connector rotation and glitchy connections.

The Nitty Gritty

The ATH-ADX3000’s open-back design allows unrestricted airflow of the diaphragm, for extremely pure audio quality with realistic soundstaging and imaging, with nearly no use of dampening material or acoustic aids. The ATH-ADX3000 features a full-range driver that is designed entirely by the engineers at Audio-Technica and manufactured and hand-assembled in Audio-Technica’s Machida, Japan factory. The driver utilizes the same technology as the company’s acclaimed flagship ATH-ADX5000 headphones.

Japanese Craftmanship

As a leading innovator in transducer technology for over 60 years, Audio-Technica places special emphasis on driver design to achieve the optimal sound from each pair of headphones. Did we mention that the ATH-ADX3000’s integrated driver units are handmade in our Machida, Tokyo, facility to ensure the highest quality? Sure did- but it is worth repeating.

Audio-Technica’s exclusive Core Mount Technology positions the driver’s voice coil in the middle of its housing, so that the acoustic space is balanced in both the front and the back of the driver. Audio-Technica lead engineer Hiromichi Ozawa noted, “Our engineers worked hard to achieve a frequency response that is not easy to obtain by using only natural air flow. Our expertise in driver technology influenced our approach to open-back headphones, and enabled us to ensure that the driver diaphragm moves with the purest motion possible.”

The ATH-ADX3000 employs a 58 mm tungsten-coated diaphragm, pure iron magnetic circuit, voice coil, and aluminum housing, which are all combined in a single integrated driver unit. The diaphragm is extremely lightweight and responsive, and the pure iron magnet enables exceptional dynamic range and high efficiency. Together, this approach creates an optimum structure that offers superb clarity and stereo imaging, with articulate bass, a smooth midrange, and detailed, extended high frequencies.

The ATH-ADX3000 is designed for long-wearing comfort, thanks to its light weight of only 280 grams. It’s supplied with a detachable 3.0m (9.8-foot) cable with A2DC connectors and comes with a robust aluminum storage case.

A2DC Connector

The Audio-Technica ATH-ADX3000 Open-Air Dynamic Headphones is available starting October 24, 2024, at a suggested retail price of $999 usd/ $1,387 cad.

Audio-Technica was founded in 1962 with the mission of producing high-quality audio for everyone. As we have grown to design critically acclaimed headphones, turntables and microphones, we have retained the belief that great audio should not be enjoyed only by the select few, but accessible to all. Building upon our analog heritage, we work to expand the limits of audio technology, pursuing an ever-changing purity of sound that creates connections and enriches lives. For the Silo, Frank Doris.

New Volume Of Guitar Music Extravaganza From Octave Records

Leave a comment

The Art of Hi-Fi, Volume 6: Guitars from Octave Records Features an Extravaganza of Playing Styles and Sounds – Octave’s latest offers a wide selection of guitar styles and genres, from solo acoustic to all-out rock on overdrive  –
September, 2024 – What’s not to love about guitar music? Especially when it’s as well-recorded and soulfully played as the selections on The Art of Hi-Fi Volume 06: Guitars, the latest release from Octave Records. The album features a wide range of artists, styles, and instruments, from the solo acoustic 12-string guitar of Bill Kopper on “Hungry Heart” to Americana, jazz, pop, well-loved covers, and Connor Terrones tearing it up on Jimi Hendrix’s “Manic Depression.” It’s all here, captured in Octave Records’ stunning Pure DSD high-resolution recording quality.

Paul McGowan, Octave Records’ CEO pointed out: “Guitars are part of the soundtrack of our lives, from sweet acoustic and warm jazz tones to the powerful electric guitar sounds that have galvanized generations of listeners. Yet it’s extremely challenging to capture these many and varied musical and sonic flavors on a recording. We are thrilled with the sound and performances of our Octave artists on The Art of Hi-Fi Volume 06: Guitars, who did a fantastic job of showcasing the almost limitless potential of the instrument.”

The Art of Hi-Fi Volume 06: Guitars was recorded with Octave’s Pyramix-based Pure DSD 256 recording system, using a variety of microphones to capture the wide variety of guitars on the album: steel-string and nylon-string, 12-string guitar, electric, pedal steel, resonator, and even baritone guitar. Everything from the crystalline overtones of a steel-string guitar to the roar of a guitar amp speaker pushed beyond its limit is here to enjoy. The album was recorded, mixed and produced by Paul McGowan, with Terri McGowan and Jessica Carson assisting in the recording and production duties. It was mastered by Gus Skinas.

The album begins with Julian Peterson’s soulful Americana-tinged “Am I Wrong” by Keb’ Mo’, singing and playing a resonator guitar using a slide, a deep, elemental sound. The bossa-nova-tinged “Amor Prohibido” features Bill Kopper on nylon-string, accompanied by bass and percussion. It’s a lively musical dialogue, beautifully recorded. Kopper and the trio also contribute “Sweet Lorraine,” played gypsy jazz style with a snappy, cutting guitar tone, and he goes solo with the gorgeous 12-string sound and complex fingerpicked voicings of “Hungry Heart.”

The wailing sound of the pedal steel guitar is featured on Greg Schochet’s country original, “Broken Down Chair,” with Schochet’s plaintive singing and sparse acoustic guitar playing carrying a wry tune about likening his life to the well-worn piece of furniture. Khabu Young contributes a dazzling instrumental version of the Beatles’ “Come Together” on solo baritone guitar, and the amount of sound he gets out of just the one instrument is remarkable.

The Seth Lewis Trio offers intimate versions of the Bacharach/David classics, “The Look of Love” and “Close to You,” featuring the warm, rich tones of Lewis’ acoustic and electric basses, along with piano, organ, and drums. Wyn Walke digs into the 1930s American classic “Deep Elem Blues,” made popular by the Grateful Dead in the 1960s, performed here in a stately version with vocals, lap steel guitar, bass, percussion, and piano. The Art of Hi-Fi Volume 06: Guitars closes with a dramatic musical shift: Connor Terrones’ incendiary instrumental version of “Manic Depression,” with multiple guitars, bass, and drums blasting away to bring the album to a roaring no-holds-barred conclusion. Turn it up!

The Art of Hi-Fi Volume 06: Guitars features Octave’s premium gold disc formulation, and the disc is playable on any SACD, CD, DVD, or Blu-ray player. It also has a high-resolution DSD layer that is accessible by using any SACD player or a PS Audio SACD transport. In addition, the master DSD and PCM files are available for purchase and download, including DSD 512, DSD 256, DSD 128, DSD 64, and DSDDirect Mastered 352.8 kHz/24-bit, 176.2 kHz/24-bit, 88.2 kHz/24-bit, and 44.1 kHz/24-bit PCM.

$7500 Phono Cartridge Supercharges Record Players

Leave a comment

STOW, OHIO, June, 2024 — Audio-Technica today announced the introduction of its new top-of-the-line phono cartridge, the AT-ART1000X Direct Power Stereo Moving Coil Cartridge. Hand built in Tokyo, Japan, the AT-ART1000X builds upon the engineering excellence of the previous rave-reviewed AT-ART1000 with improvements in design and materials, and threaded mounting holes for easier installation.

Innovative New Design

Unlike conventional moving coil cartridges, the AT-ART1000X’s Direct Power System places its dual moving coils on top of the stylus tip rather than at the base of the cantilever, enabling the cartridge to deliver extraordinary fidelity with greater musical detail. The AT-ART1000X’s coils are now rectangular rather than round, which positions more of their surface area in the magnetic field. This provides improved reproduction of record groove modulations, along with a higher output voltage for better signal-to-noise ratio and an expanded low-frequency range.

“By placing the moving coils, which convert the motion of the stylus and cantilever into electrical signals, directly on top of the stylus, the effects of the cantilever’s length and material type are minimized,” noted Yosuke Koizumi, Audio-Technica Cartridge Engineer. “This design and the additional refinements we’ve made to the AT-ART1000X achieve a new level of sonic realism, with remarkable resolution, tonal and spatial accuracy, and dynamic impact.”

Pure Copper Coils Make A Difference

Each of the AT-ART1000X’s two moving coils is made of 20 µm diameter PCOCC (Pure Copper by Ohno Continuous Casting) wire, hand-wound in eight turns to create a 1.1 mm x 0.6 mm (0.043 in x 0.024-inch) rectangle. The coils are contained in an ultra-thin 25 µm (0.98 mil) special film and housed in an 0.5 mm (0.020-inch) gap of the powerful magnetic circuit (smaller than the previous 0.6 mm gap), enabling each coil to generate a higher 0.22 millivolt output with a 3.5-ohm coil impedance, despite having a non-magnetic core.

The AT-ART1000X employs a special line-contact stylus and solid boron cantilever for superb accuracy in tracking the record groove.

The support base for the magnetic circuit, stylus and cantilever is made from titanium. The base, and the cartridge’s aluminum housing and hard plastic cover all operate together to disperse any internal resonances that would otherwise affect sound quality. In addition, a special coating protects the magnetic circuit from corrosion. The musical result is rich, natural full-bodied reproduction of vocals and instruments, with weight, presence, and depth, presented on an expansive soundstage.

The Audio-Technica AT-ART1000X Direct Power Stereo Moving Coil Cartridge is now available at US$5,499.00/ CAD$7,574. For the Silo, Jamie Bobek.

The ATH-AWKG headphones (SRP: US$4,200 / CAD$5,650) are equally exceptional. Like the HPA-KG NARU, the headphones are handcrafted in Tokyo, Japan, from rare kurogaki wood. In addition to its distinctive appearance, the acoustic properties of the kurogaki housings contribute to the headphones’ extraordinary sound quality. The hand-applied lacquer finish brings out the wood’s natural beauty.

Audio-Technica NARUKAMI ATH-AWKG Closed-Back Dynamic Wooden Headphones

The ATH-AWKG features purpose-designed 53-mm drivers with Permendur magnetic circuitry. Each driver is equipped with a titanium flange and a 6N-OFC high-purity oxygen-free voice coil to ensure precise movement and optimum signal transfer. Audio-Technica’s exclusive D.A.D.S. Double Air Damping System provides smooth, accurate bass response.

The ATH-AWKG is designed for maximum long-wearing comfort, and is supplied with an additional set of ZMF Universe Hybrid earpads for a unique alternate listening experience. The headphones are equipped with Audio-Technica’s A2DC jacks and two 9.8-foot (3.0 mm) detachable cables with 4-pin balanced and standard 1/4-inch jacks. Adding to its elegance, the ATH-AWKG comes in a presentation box with kurogaki wood accents.

Audio-Technica was founded in 1962 with the mission of producing high-quality audio for everyone.

It’s available in a striking new matte finish in either black or white, and comes with magnetically detachable grilles. The aspen FR10’s room-friendly design makes it easy to set up and enjoy, and the FR10 comes with a handy setup booklet and CD to get the most out of the speaker. The FR10 has a visually distinctive “floating” appearance, with a curved bottom and an anodized aluminum base that is supplied with mounting feet that can be used with either removable stainless-steel spikes, or a soft rubber foot underneath.

The aspen FR10 delivers remarkable loudspeaker performance in every respect, with authoritative bass, an inviting midrange, smooth, extended highs, wide dynamic range, and palpable imaging on a wide and deep soundstage. It’s sure to thrill even the most demanding audiophiles and music aficionados.aspen FR10 Features at a Glance:

We are thrilled to be able to present this music for everyone to now enjoy.” Recorded live in the studio, the album captures the confident yet relaxed interplay that only comes from years of playing together, with Ron joined by Andrew Vogt (tenor sax, baritone sax, clarinet, flute), Curtis Fox (trombone), Dave Weinand (bass) and Andreas Schmid (drums).The quintet performs a host of Charlie Brown tunes like the familiar “Linus and Lucy,” the “Charlie Brown Theme,” “Christmas is Coming,” and others, along with jazz-laced versions of pieces from The Nutcracker including the iconic holiday classic “Dance of the Sugar Plum Fairy.” Added to the mix, the quintet plays a wry, swinging take on “You’re a Mean One, Mr. Grinch.”Alfredo Muro is a concert guitarist, composer, arranger, and improviser. He’s been described as a Latin guitar virtuoso, yet his styles and tastes are far more wide-ranging, from the classical repertoire to folk, jazz, Brazilian and more. He noted, “The idea of the program presented on The Spirit of Christmas was to choose traditional Christmas themes, combined with Christmas music popular in Spain and South America. Many of those songs are connected to my heart – they are part of my childhood in Latin America.”

The selections range from holiday standards like “Silent Night,” “The Christmas Song” and “White Christmas” to spiritual works such as “Jesus Bleibet Meine Freude” (“Jesu, Joy of Man’s Desiring”) and “Ave Maria, and songs that are deeply personal to Muro including “Preludio de Adiós” and “El Noi de la Mare.” Muro’s Paco Santiago Marin classical guitar has a deeply rich tone with a wide color palette and superb dynamic nuances, all captured in remarkable fidelity. On “Villancico de Navidad,” Alfredo is joined by guitarists Robert Chirico, Adam Buer and Felicity Muench and bassist Allen Bossard, to close The Spirit of Christmas on a beautiful and graceful note.

The albums, available on disc or via download, were recorded, mixed and produced by Paul McGowan at Octave Records’ studio, with assistance from Jessica Carson, Alfredo Muro, Ron LeGault, and Terri McGowan. Both albums were mastered by Gus Skinas. Charlie Brown Goes to The Nutcracker and The Spirit of Christmas feature Octave’s premium gold disc formulation, and the discs are playable on any SACD, CD, DVD, or Blu-ray player. They also have a high-resolution DSD layer that is accessible by using any SACD player or a PS Audio SACD transport.

Combining Bass Loudness & Decay Times To Improve Stereo Quality

Leave a comment

Research from acoustics scientist Dr. Floyd Toole indicates that bass quality accounts for about 30% of your system’s sound quality.  So, I’ve experimented with target curves that raise the bass loudness relative to other frequencies and added bass traps to reduce its decay times to improve my system performance and satisfaction.  My experiments are on top of already “perfectly time aligned” and EQ’d subs and main speakers via FIR convolution correction filters using Audiolense software.  OmniMic software is used to measure decay times and frequency response.    I’ll summarize my experience below.

Room Layout and Bass Trap Types

My living room layout (25′ x 11.25′ x 8′) is open on the left and right sides to a dining room and foyer and long hallway respectively.  At the back of the room on the right side it’s open to a den.  While these openings may act like bass traps allowing bass waves to escape before bouncing back with less energy, there is still much that can be done to improve the overall bass quality.  I use 25 bass traps, most in the listening room but 4 in a foyer/hallway, and 1 very large DIY in the dining room and den.  Six traps are “pressure” types that use a membrane to absorb bass, while the rest are “velocity” type traps that use insulation and friction to turn bass waves into heat.  Typically, pressure bass traps work below about 100Hz while velocity traps work above it.  Therefore, they are complimentary and both are needed when a system plays to the lowest bass notes.  Pictures of my room and trap locations follow.

Front Wall Trap Placement

Picture 1 above shows large bass traps in each front wall corner extending upwards to the ceiling.

Left Side Wall Trap Placement

sept 27 Left side wall1.jpgPicture 2 above shows black membrane traps on the floor against the wall (with boards atop) and a black velocity trap on its side on the far left.  Additional traps are behind the couch.

Back Wall Trap Placement

sept 27 Back wall1.jpgPicture 3 above shows the back wall with alternating white RPG Skyline diffusion and GIK Monster Bass Traps with FlexRange elevated above and behind the couch, while more GIK traps sit behind the couch on the floor.

Bass Loudness

It’s worth noting my preferred target curve to boost the bass frequency loudness is as follows:
250Hz is XdB
125Hz is X+1dB
63Hz is X+3dB
30Hz is X+6dB
This is a gentle almost logarithmic increase to partially-match our hearing’s “equal loudness curves.”

Bass Trap Positioning Affects Decay Times

If bass wavelengths are long and omni-directional, then traps can just be spread around the room I thought.  Well, in my room, it turns out that placing traps in the adjoining rooms and hallway helps to reduce bass decay times but not by as much as when the traps are moved and placed closer to the mic or speaker positions.  The membrane pressure bass traps for <100Hz were more effective when placed in a three-surface corner and in front of rigid concrete support walls where bass pressure is highest, and less effective in front of less rigid drywall etc.  The insulation filled velocity bass traps for >100Hz were sensitive to air space depth behind them, and I was surprised to find some places where they made little effect – not every wall is equal.  Trial and error and measurements helped find their best positions.

Calculating Decay Times

If your room is enclosed (and not open to the rest of the house), then one of the theoretical equations may work for you:
Decay Time = 0.3 X [(Cubic Room Volume/3532)(1/3)]
Divide your cubic room volume by 3532, then take the cubed root, and then multiply it by 0.3 which equals the average decay time based on room size.

However, if your room is an “open concept” or “great room” open to other rooms and hallways like mine, then the theoretical equation may not be best.  I prefer to measure decay time in 1/3 octave intervals and take the average from 20-20khz and then add/subtract 15% to represent an upper/lower limit respectively.  Each channel is measured separately to spot any anomalies and then their averages are combined as a single average decay metric.

Bass Ratio and “Warmth”


Perceived bass warmth is its loudness and decay times relative to mids/high frequencies and is a personal preference.  Perceived bass warmth factors include:
> frequency response (e.g. desired target curve to boost bass frequency loudness)
> decay time (e.g. absorption amounts)
> room acoustics (e.g. dimensions, materials, furnishings & acoustic treatments)
> personal preferences (e.g. preferred musical genres)

Musical genres seem to influence how much bass warmth we enjoy.
> Genres with More Bass Warmth: jazz, blues, R&B, soul, classical, reggae, folk
> Genres with Less Bass Warmth: electronic dance, rock, metal, pop, hip-hop

In attempts to quantify perceived bass warmth, I borrowed the “Bass Ratio & Warmth” metric found in F. Alton Everest’s book “Master Handbook of Acoustics” used for large spaces like auditoriums and concert halls.  It uses 2 bass octaves (centered at 125Hz and 250Hz) and compares it to the 2 midrange octaves above them (centered at 500hz and 1KHz).    Because it’s based on a ratio, it should work for smaller domestic rooms also I recon.  While large spaces use the RT60 metric for decay time, I prefer the T40 for domestic rooms.  It’s calculated as:
Bass Ratio & Warmth = [T40(125hz)+T40(250Hz)] / [T40(500hz)+T40(1khz)]  =  should be from 1.1 – 1.4

This means that the 2 bass octaves used in the formula have decay times 10% – 40% longer than the 2 midrange octaves (i.e. a 1.4 value is warmer than 1.1).

At one point I managed to get my bass ratio down to 1.2 which sounded a tad thin based on what I was used to hearing previously.  To compensate, I boosted the sub’s volume a bit.  Today’s ratio is 1.3 which sounds better to my ears likely because it is closer to how I’ve always had it but  I no longer boost the sub’s volume.  I might experiment with shifting the entire equation down one octave as I suspect my music with synthesized bass lines run deeper than an orchestra, so the calculation would be:
Bass Ratio & Warmth = [T40(63hz)+T40(125Hz)] / [T40(250hz)+T40(500Hz)]  =  maybe 1.2 – 1.5?

If bass warmth is affected by relative loudness and decay times, then how do we combine them into a workable ‘model?’  One way is to recognize that I can get bass warmth under two opposing situations: (A) short bass decay times but louder bass frequencies, and (B) longer bass decay times but with attenuated bass frequencies.  

The downside of (A) Short Bass Decay Time with Louder Bass Frequencies
> thin sounding as if harmonics are missing
> lacks a certain fullness
> possible listening fatigue from having the bass volume turned higher

The downside of (B) Long Bass Decay Time with Attenuated Bass Frequencies
> muddy or boomy sound where individual bass notes are not defined resulting in reduced clarity
> less clear midrange
> bass modes may be triggered for an unsmooth frequency response

And in between these two opposing situations is a continuum of possible situations that I attempt to show in Chart 1 below.

Tips

  • For starters, the subwoofers need to be perfectly time aligned with the main speakers as a minimum.  Use measurement software and impulse responses or get equipment like miniDSP or with DIRAC or ARC capabilities. or Audiolense to generate FIR convolution files.  If you only have analog sources then pull the subs ahead of the mains due to the sub’s group delay until they sound lockstep with the mains.
  • EQ bass peaks using FIR filters ideally or use DSP within JRiver/ROON or miniDSP, or graphic eqs as a last resort.  Measurements are a must.
  • Install both types of bass traps to augment each other and extend the absorption down to 40Hz or lower.  I’ve found that open concept rooms will naturally have lower high frequency decay times so you’ll likely need more bass traps to try and bring the bass decay times down and in line with the mids/highs compared to an enclosed room.
  • Take decay measurements as you move bass traps from one location scenario to another – it’s tedious work.  Try and achieve different Bass Ratios to hear how different they sound and take notes so you can revisit your best sounding scenario.  You want to strive for as flat a decay line through mids/highs with the bass about doubling the mids’ decay time.  Aim for 200 – 500ms decay time with the high end for stereo and the low end for Home Theatre.  Each speaker should have about the same decay times across the tested frequencies (i.e. little inter-speaker decay variance).
  • Try and preserve your mids/high decay times through reflections of hard surfaces like diffusion, or bass traps that have a membrane of sorts that reduce its absorbency of mid/high frequencies (e.g. GIK Monster with FlexRange).  Air acts as a natural absorber from +2KHz, and so does an open concept room that doesn’t allow the highs to reflect back with much energy. 
  • Experiment with different Target Curves that boost low bass frequency loudness.  

Want Less Bass Boom/Warmth?

If you want less bass warmth then: (i) move the starting point of the bass loudness boost from 250Hz to 150Hz or 100Hz (ii) use a less steep target curve to reduce the amount of boost at the lowest frequencies (iii) move speakers away from walls that reinforce bass (iv) add bass traps to reduce decay times and modal ringing (v) move your listening chair (vi) EQ out bass peaks.  

When assessing the perceived warmth of bass, consider frequency response loudness levels across bass and midrange frequencies and their decay times.

Chart 1 above shows how bass loudness and bass decay times can be combined to provide good bass quality from subtle to pronounced warmth.  For the Silo, Kevin Fielding.

User Experience is Everything

The nwm MBE001 on-ear speakers are thoughtfully designed to address numerous factors that directly impact user satisfaction. These key benefits include:

  • 51Gt077ygXL._AC_SX679_.jpgReduced audio escape for utmost privacy. 
  • These earphones feature “PSZ Technology” creating a Personalized Sound Zone, which reduces audio leakage and ensures a private audio experience … whether that be a conversation, music, video or any other sound source. The PSZ technology resolves the long-lamented sound leakage problem, finally allowing users to listen to music, audiobooks, phone calls and attend online meetings in cafes and other public spaces with peace of mind.
  • Balanced listening comfort. In addition, the nwm MBE001 open-ear speakers offer balanced listening comfort by not blocking the ears, allowing users to hear ambient sounds and even their own voice clearly. The 12mm diameter drivers provide a natural listening comfort, similar to listening to background music, allowing a unique and equitable listening experience both through and outside of the earphones. Perfect for those who frequently use online communication, the open ears make it easy to speak without blocking the sound of your own voice.
  • Situational awareness and interaction. Because the device is not inserted inside the ear canal and does not block the ears, users can engage in natural conversations with people around them … even while listening to music or any other audio. They no longer have to remove the device when paying at the cash register, asking a quick question at the gym or responding to co-workers. Most importantly, users can remain alert to the sounds of approaching cars and other possible hazards—fostering potentially life-saving situational awareness.
  • Superior sound quality. Advanced sound technology allows users to experience crystal-clear audio. These on-ear speakers deliver rich, balanced sound across all genres, elevating the music listening experience to new heights.

They are not just about sound, but rather connection as they offer a new way of engaging with the world … complete with your very own Personalized Sound Zone. With them, you’re in tune with your world by being in control of your sound.”

Revolutionary Technology


NTT sonority’s journey taking the nwm MBE001 wireless on-ear speakers from concept to product launch was marked by countless trials and adjustments to balance sound pressure and quality while minimizing sound leakage. The company’s PSZ technology is a key innovation that applies the principle of noise cancellation by producing an inverted soundwave to neutralize sound. Unlike conventional audio devices that house the speaker unit in a box to prevent interference, PSZ technology has redefined this norm by confining sound within a 360-degree radius around the ear to minimize sound leakage. This non-directional speaker design offers stress-free, continuous listening without the pressure or vibrations associated with bone conduction earphones.

0-HelloWorld.jpg

To incorporate PSZ technology into the nwm MBE001 on-ear speakers , the company had to reduce the size of the speaker units to their smallest possible dimensions. The challenge was to maintain sound quality while achieving sound pressure in the ear. The unique approach of using the inverted waveform from the back of the speaker to cancel out sound has also led NTT sonority to undertake R&D on both aircraft seats that provide a more private acoustic space as well as automobile seats that allow different audio playback for each user—all to improve comfort in ground and air transport vehicles WITHOUT using earphones or headphones. The ability to enjoy audio comfortably in a private space will make long journeys more enjoyable and comfortable while also enabling seamless communication with those around you.

The isolation base’s construction features a spiked platform with an improved version of Nola’s ball-bearing isolation technology incorporated into the base.

While the concept may seem simple, the results are profound.

Nola president Carl Marchisotto noted, The idea was inspired by attending a recent live music concert. You can instantly tell live from reproduced music, and I wondered why. I was struck by the fact that with live music, the harmonics decay properly with respect to the fundamental. They’re not lost, or cut off abruptly. I set out to make sure this important aural cue was preserved, by designing the new isolation base, and achieving further improvements in performance with our new low-distortion drivers and upgraded crossovers. Marchisotto continued, For the first time, we will demonstrate our ball bearing isolation system applied to the whole system, including the source, amplification and other components as well as the loudspeakers.

The true ribbon tweeters, which are built with final assembly completed in-house with proprietary components, have a frequency response to 100 kHz, for smooth, effortless high-frequency reproduction.

The midrange drivers incorporate Alnico ring magnets for a more lifelike attack and transient response, and now feature the same gold-plated phase plugs used in the woofers. The 220 mm woofers employ magnesium cones and massive Alnico ring magnets, and are housed in individual rear-ported chambers for deeper, more articulate bass with exceptional dynamic response. The 3-1/2-way crossover network is hand-wired with premium components and no PC boards used, to maintain sonic purity.

These speakers have what designers and reviewers used to call the jump factor, where they can surprise you with their dynamic impact and clarity, Marchisotto said. You don’t realize that certain distortions in a loudspeaker are eliminated until you don’t hear them, in a speaker that brings you closer to musical reality. We invite everyone at Pacific Audio Fest to come by and enjoy a very special listening experience.

The Nola Baby Grand Reference Gold 3 is available in mirror-imaged pairs in a choice of True Piano Black Gloss or True Piano Santos Rosewood finishes, with other finishes and colors available by special order. The Baby Grand Reference Gold 3 is now shipping at a suggested retail price of $150,000USD/ $198,190CAD per pair. For the Silo, Frank Doris.

Genelec 8381A point source main monitor delivers unrivaled power and precision

NATICK, MA, May 16, 2023 — As part of its 45th anniversary year, Genelec has unveiled the 8381A Smart Active Monitoring system, a flagship floor-standing Adaptive Point Source™ design that fuses exceptional precision and envelopment with unrivalled LF control, huge headroom and high-resolution imaging. Designed for high-end music recording, mastering and audiophile listening, the 8381A creates a free-standing full-range monitoring solution that can intelligently adapt to any acoustic environment.

For audio professionals, the 8381A produces accurate full-band mixes that translate consistently to other rooms and playback systems, while audiophiles will experience every detail and nuance of a musical performance, just as the creators intended it to be heard.  

I first encountered Genelec powered monitors (more specifically monitor- more on this below) while on a scholarship at the Banff International Center for the Arts in Alberta, Canada. At that time (2010) I was unfamiliar with Genelec and had faith in the school’s choice of equipment: all the other available items were top notch.

Rosa Maria Robinson Bours

I settled on a single Genelec speaker as I was planning on a series of live mono recordings taking advantage of the talented classical guitar and voice cohorts such as Rosa Maria Robinson Bours. When the Genelec was delivered to my artist studio I was intrigued. It looked quite compact, it was black as soot and seemed to be as heavy as lead. After positioning and connecting the monitor I was blown away by the power, clarity and transparency for test playback and also while mixing and mastering tracks.

Let’s get back to the newest Genelec

As a member of “The Main Ones” range, the 8381A system is acoustically coaxial right down to bass frequencies, and draws on proven technology developed for Genelec’s patented and award-winning “The Ones” family of point source monitors and the W371A Adaptive Woofer System, which themselves can combine to create a free-standing full-range monitoring system. However, the 8381A raises the performance bar even higher by offering controlled directivity and uncolored response both on and off axis, with an ultra-wide frequency response spanning from 20 Hz to 35 kHz. Additionally, with almost 6 kW of amplifier power and a staggering maximum SPL of 126 dB – the highest figure ever achieved by a precision point source acoustic design – the 8381A offers the most sophisticated features and specification of any audio monitor currently available.   

At the heart of the 8381A is a proprietary high SPL Minimum Diffraction Coaxial (MDC™) midrange/tweeter driver, which – combined with a powerful Genelec DSP engine – delivers extraordinary clarity, imaging and adaptability. This MDC driver shares a common acoustical axis with the 8381A’s four complementary 5-inch dome drivers, which are arranged as a midrange transduction system, and this unique array combines with a forward-facing 15-inch woofer to provide outstandingly stable directivity, control and coherence.  

To further enhance and extend the 8381A’s low frequency reproduction, a pair of high-performance 15-inch woofers employ the LF adaptive technology originally developed in the W371A, offering high resolution and supreme levels of low-frequency control – despite the effects of room acoustics. This technology allows the 8381A to tailor performance carefully to the room, offering flatter, smoother in-room response at the listening location, with LF imaging coherent with the full audio range. This flat and neutral LF response minimizes acoustic notching, and reduces detrimental reflections and resonances by the walls, ceiling or floor of the room.    

As part of Genelec’s Smart Active Monitoring family, the 8381A integrates tightly with Genelec’s GLM software, which can configure, calibrate and control entire Genelec smart monitoring systems. Based on experience from thousands of studios around the world, GLM minimizes the listening room’s influence on the sound, enabling the user to produce mixes that translate perfectly to other systems, whether the format is stereo, surround or high channel count immersive.

GLM also includes the ground-breaking GRADE room report feature, which gives the user a complete analysis of their room and monitoring system performance, providing specific observations and advice on any acoustical issues, helping users and studio designers alike to fine tune the room’s acoustic treatment, adjust monitor and listener positions, and optimize bass management.

Designed and manufactured to the highest standards of sustainability and environmental responsibility at Genelec’s headquarters in Iisalmi, Finland, the 8381A comes with a comprehensive SonicAdvisor™ system calibration and service package to jointly celebrate Genelec’s 45th anniversary, and the company’s total commitment to its customers and to sustainable development.   

“The demand for high quality free-standing full-range monitoring systems has been clear from the exceptional response to The Ones and W371A combination,” comments Genelec Managing Director Siamäk Naghian. “It was also evident that there was a desire from customers for a free-standing system that could deliver even more headroom and increased low frequency extension. And while we continue to offer a wide range of soffit-mounting main monitors, we’re confident that the flexibility and mobility of a floor-standing adaptive system like the 8381A will provide the perfect solution for any discerning user seeking a truly next-generation sonic reference.”   For the Silo, Jarrod Barker.

Octave Records Debuts The Audiophile’s Guide: The Loudspeaker, the Definitive Guide to Speaker Setup

–  New book and companion SACD disc/download dive into exacting, step-by-step detail on how to get the most out of any loudspeaker –

Boulder, Colorado, October, 2022 – PS Audio’s Octave Records label announces its latest release, The Audiophile’s Guide: The Loudspeaker, a book and companion SACD/download that tells listeners exactly how to get the most out of their loudspeaker setup. Written by PS Audio CEO Paul McGowan, the book and its accompanying disc (also available as a download) offer the practical knowledge he’s gained through more than 50 years of high-end audio design and in setting up hundreds of speaker systems.


 
“I’ve had to come to the rescue of someone’s system time and again because it just wasn’t sounding right. It was almost always a setup problem. Like everyone else, I used favorite music tracks for system tuning. But now, with Octave Records’ recording studio at our disposal, we were able to create tracks that are ideal for system setup, and then write a book that tells listeners how to implement these tracks to their best advantage.”
 
The Audiophile’s Guide: The Loudspeaker is useful for both novices and experienced audiophiles who may benefit from bringing their setup to a higher level or musical realism.

The book begins by covering a variety of topics including the nature of sound, different speaker designs, the importance of choosing the right speaker for your particular needs and listening tastes, and one of the most critical aspects of speaker setup: the effect of the listening room on loudspeaker performance.
 
Next the book discusses where to place the speakers in the room, and how to deal with various types and shapes of rooms. The Guide notes that different placements may be appropriate for different speaker types – for example, stand-mounted “box” speakers versus dipole planar designs – and listening room configurations (such as whether to place speakers across the short or long wall of a room). Real-world aspects like accommodating living spaces that aren’t dedicated to loudspeakers, and taking into account the locations of furniture, are also considered.
 
The Audiophile’s Guide: The Loudspeaker (SRP: $58usd/ $79 cad – $68usd/ $93cad depending on format) then walks the listener through using the accompanying reference disc (or download) to fine-tune the system to perfection. The disc starts with some basic tests for channel orientation and moves on to exacting, step-by-step procedures (time to get out the tape measure!) for getting the best bass response and tonal balance, achieving a solid center image, finding the best seating position, maximizing dynamics, producing a believable soundstage, capturing subtle musical details, and ultimately, getting the speakers to “disappear” and create the feeling that the musicians are in the room with the listener.


 
The tracks on the disc are tailored to help the listener zero in on various sonic aspects, from the pluck of Chris Brunhaver’s acoustic bass and how it energizes the room, to the focused center image of Gabriel Mervine’s trumpet, and the resonance and spatiality of Bill Kopper’s acoustic guitars and a number of tracks featuring vocalists with a full band.

The Recording

Recorded over three months of intense work, The Audiophile’s Guide: The Loudspeaker was the first recording project at Octave Records’ new state-of-the-art studios. Recorded in pure DSD256 and mixed by Paul McGowan and Jay Elliott, the tracks on this work were laid down with every effort to maintain not only the purity of recording, but the accuracy of mic’ing, distance, and purpose. The mic’ing on solo voice, piano, trumpet, and guitar was primarily handled with a single-point stereo microphone to maintain a sense of realism. In particular, Octave Records’ hand-modified AKG C24 was used throughout the many tracks. On other tracks, like guitarist Bill Kopper’s seminal work focusing on the beauty of ringing harmonic overtones, we blended the detailed stereo condensers of the single-point Telefunken with the dynamic impacts of a single-point stereo ribbon microphone. Engineers Jay Elliott and Zach Balch went all out to get the best recordings from an amazing drum kit.

The Ludwig Supraphonic snare drum used on many hit records.

The kit (the same kit used in The Audiophile’s Guide: The Stereo) consists of a Ludwig 1970 Blue Sparkle 20” kick drum, 12” rack tom, 16×16” floor tom, 14 x 6.5” Ludwig Superphonic John Bonham LM 402 snare drum, Zildjian New Beats Hi-hat 70’s era 14”, Custom Dark Crash Kerope by Zildjian Crash 18”, and a Kerope by Zildjian 22” ride. To capture this kit, Jay and Zach employed their favorite setup for close mic’ing: a Shure Beta 52 for the kick-in and a cardioid patterned, phantom powered, large-diaphragm FET Soundelux U195 by David Bock for the kick-out. The top of the snare was handled by a Hypercardioid Beyerdynamic M201 with its phase flipped while the snare’s bottom was a Telefunken M80. The rack tom was captured by a Shure SM7B Cardioid dynamic microphone and the floor tom, an Audix D4 hypercardioid dynamic microphone.

The earlier Shure model SM7 was used to record Michael Jackson’s vocals for the Thriller album.

To capture the ambient room response, a pair of calibrated DPA omnis were used for the overheads, and the stereo AKG C24 in a Blumlein configuration was placed twelve feet into the room for space recording. All microphone preamplifiers were Manly vacuum tubes with a small smattering on the overheads using Forsell preamps. The tracks were all mixed in Octave Records’ custom mixroom on PS Audio’s aspen FR30 loudspeakers powered by an all-PS Audio system.


 
The Audiophile’s Guide: The Loudspeaker SACD is playable on any SACD, CD, DVD, or Blu-ray player (an SACD player is required to play the high-resolution DSD files on the disc). In addition, the master DSD and PCM files are available for purchase and download in formats up to 352.8 kHz/DSD256 from psaudio.com at this link.

Octave Records Releases Temporary Circumstances by Clandestine Amigo, Recorded in Pure DSD Hi-Res Audio 

  • PS Audio label’s second release featuring singer/songwriter Jessica Carson is available on SACD and via download, with limited-edition vinyl to come – 

Boulder, Colorado, October, 2020 – PS Audio’s Octave Records label has released its second album, Temporary Circumstances by singer/songwriter/pianist Jessica Carson and the band Clandestine Amigo. Featuring Jessica’s reflective songs about lost love and resilience, Temporary Circumstances is recorded in pure high-resolution Direct Stream Digital (DSD) and mastered using Octave Records’ DSD Direct Mastering process, where the mastering occurs at the same time as the mixing, thereby eliminating a generation of audio processing to maintain maximum sonic purity.  

Limited Release

Temporary Circumstances is available in a limited-edition release of 1,300 hybrid SACD discs that have a master DSD layer and a CD layer, and as a download bundle including DSD64, DSD Direct Mastered 192kHz/24-bit, 96kHz/24-bit and 44.1kHz/24-bit PCM formats. The album will also be offered as a 2-disc 45 RPM virgin vinyl edition limited to 500 copies, in December, 2020. 

Temporary Circumstances was engineered by Gus Skinas, mixed by Gus Skinas, Giselle Collazo and Jessica Carson, and mastered by Gus Skinas. The recording was made using a Sonoma digital audio workstation (DAW) in pure one-bit DSD. The C24, DPA 4006 and Sony C-100 microphones were fed into Forsell SMP-2 and Grace m108 mic preamps and an EMM Labs/Meitner ADC8 A/D converter, then to the Sonoma, and mixed on a Studer 963 console. 

Bit Wars

Currently, most DSD recordings have a short fall in that they must be converted to PCM and back to DSD a multitude of times in order to perform post production such as mixing and mastering. This is where PS Audio ups the ante- by mastering during the mixing phase, the back and forth conversion which results in noticeable degraded listening experiences is avoided.

The ‘old’ PCM pulse code modulation system.
The ‘new’ DSD direct stream digital system.

The musicians include songwriter Jessica Carson (vocals and piano), Michael Wooten (drums), Giselle Collazo (vocals), Chris Brunhaver (bass), Kyle Donovan (guitar, vocals), Miguel Ramos (violin, viola), and “The Burroughs” horn section featuring Alec Bell (trumpet), Scott Flynn (trombone), Hayden Farr (baritone saxophone) and Briana Harris (trumpet, horn arrangement). 

Jessica recorded her piano parts on a Yamaha 7-1/2-foot concert grand piano at Animal Lane Studios in Lyons, Colorado. Next, the vocals and other instruments were tracked at Octave Records’ recording facility at PS Audio. Jessica’s lead vocals and Giselle’s harmony vocals were recorded simultaneously using a single Tim de Paravicini-modified AKG C24 stereo mic and a Bock Audio 507 mic. Temporary Circumstances’ sparse but full-bodied arrangements let the personality of each vocalist and player be heard with stunning clarity, presence and dimensionality. 

Audiophiles Take Note

The goal of recording and producing Temporary Circumstances was to combine musically accurate, state of the art sound with inviting and compelling music. As Jessica Carson notes, “I know what the songs mean to me but I think they’ll mean something different to every listener.” 

For the Silo, Frank Doris.

Supreme Analog Vinyl Record Weights Trending

Leave a comment

“If there is no sound philosophy in making the audio gear, then all product you make is plagiarism.” Zoran Mihajlovic
Having grown up around record players of dubious quality, I remember very clearly my first ‘real’ turntable. An audiophile friend of the family helped my father put together an entry level system for my 15th birthday. The system included 3 way Acoustic Research speakers, Sansui integrated amplifier, Sansui 3 head cassette deck and my first decent turntable- a gently used Sansui direct drive with a shiny S-arm and what looked like a strange silver hockey puck.

At 15 I was into my second year of drumming and with this turntable was now able to play along to LP records without having to worry about the inevitable skipping that the cheap family record player performed almost every time I hit the bass drum hard. I later learned that the puck was actually a custom made record clamp that the previous owner had fashioned to squeeze every last bit of performance out of the record player.

There is a surprising amount of science behind the advantages of using record clamps to ‘push’ the vinyl down onto the slipmat and platter and people that use them swear by them. In general terms, the added mass from the fitted clamp flattens warps in the record and a beneficial flywheel effect takes place once the record is spinning at speed.

Today, turntable designs have advanced and exotic materials and technologies are incorporated into high end models. This has translated into a need for ultra high quality clamps designed to properly secure records to all kinds of esoteric spindles and platters.

Enter Zoran Mihajlovic- a man devoted to producing the highest quality record clamps such as the Model 1 via his Serbian company Supreme Analog. At 3000 euros (at time of this article, 1 euro = 1.5 Canadian dollars) , this is a record clamp (Supreme-Analog calls it a record weight) that is produced on order only and commands attention.

Supreme Analog Model 1 record weight
70mm wide, 50mm high, 460g weight
Swiss stainless steel and Serbian sinked wood

Supreme Analog Basic Line Record BL006 stainless steel
If you are on a more modest budget, they also offer the BL-006 for 250 euros. Also made from Swiss stainless steel, the more basic model weighs in at 950g and ships world wide for free in a solid wood box.

It’s easy to tell that Supreme-Analog have a real passion for audio and they make a number of interesting products including jewel like tonearms and gorgeous horn speakers. Check them all out.  For the Silo, Jarrod Barker.

The Edifier R1280T are an affordable, entry-level set of bookshelf speakers that deliver clear and balanced sound at low or high volumes. For only $124.99CDN including free shipping to Canada these speakers set a new standard for affordable quality.

It’s a journey to provide an exceptional audio and visual experience with design elegance, innovation, features and measured risks, for whatever the application, to form a lasting end-user impression and experience.”

Edifier R1280T Speaker Back R1280T powered bookshelf speakers lets you connect to multiple audio devices using the dual RCA inputs. By looking at the back panel you can easily tell one of these is a passive speaker and one is an active speaker. The active speaker has two inputs located on the back. These inputs are perfect for RCA to RCA or RCA to AUX connections. Connect them to a PC, laptop, tablet, phone or record player. The speakers are connected to each other via regular speaker wire (included along with a generous variety of cables to ensure you enjoy your music from most devices right out of the box- if you require digital connections or bluetooth Edifier make a larger model).

 

Some overseas manufacturers of electronics have been questioned about their environmental impacts and strategies but refreshingly, Edifier are committed to best operating practices.

  • Use suppliers of raw materials who practice environmentally friendly manufacturing.
  • Use LED and T5 lighting in all office floors and manufacturing facility.
  • Install solar panels for water heating.
  • Use Biological Liquid Processing to reduce and filter fume emissions.
  • Use Membrane Bioreactors to recycle waste water

For environmentally conscious, budget minded individuals looking for a solid entry level speaker with the convenience of remote control and easy hook-up you can’t go wrong choosing the R1280T. Highly recommended.

We spent several days and evenings having fun with these speakers in a small bedroom Laserdisc and projector bookshelf setup. The sound quality was quite nice, dialogue was easy to understand and stereo soundtracks came to life, even with a noisy air conditioner running and the fan noise from the projector.

The speakers will most likely benefit from a break in period as new drivers tend to have a slight compression effect that is alleviated as the speaker suspension is stretched from playing source material. These speakers fit nicely onto the shelf and were easy to position and operate, we were pleasantly surprised by the handy mini remote control that arrived with batteries included. For darker watching conditions we left the front grilles in place but would be happy to remove them and show off the nicely designed faux woodgrain cabinet sides in brighter conditions. Highly recommended…
