Boulder, Colorado, September, 2024 – PS Audio now offers its Stellar Strata MK2 integrated amplifier, with updated features including a moving-magnet/moving coil phono stage, a built-in improved high-resolution DAC, a Class A analog preamp stage, a headphone output, 150 watts of output power, and more.



Paul McGowan, PS Audio CEO noted, “The Stellar Strata MK2 significantly improves upon the original Strata concept of providing a superb-sounding, versatile high-end integrated amplifier. Designing the Strata MK2 gave us the opportunity to implement our latest technical advancements in an all-in-one audio component that offers exceptional sound, has an attractive, compact design, and is easy to use.”

Analog enthusiasts can now enjoy the benefits of superior vinyl playback, thanks to the PS Audio’s Stellar Strata MK2’s new moving magnet/moving coil phono stage. Two stereo pairs of MM and MC RCA phono inputs are provided, plus two RCA and XLR line-level inputs. The Strata MK2 features fully balanced analog preamplifier circuitry.

It’s equally flexible in accommodating digital sources.

The Strata MK2’s built-in DAC can deliver up to 384kHz digital audio (depending on the source), with native DSD capability up to DSD256. The Strata MK2 includes one optical and two coaxial digital inputs, plus asynchronous USB and two I2S inputs. For headphone listeners, the Strata MK2 offers a top-quality Class A headphone amplifier.

The DAC utilizes PS Audio’s exclusive Digital Lens technology to deliver extraordinary sound quality from any digital source. All digital signals are fed in native mode into the DAC’s proprietary Digital Lens, which recognizes the sample rate, re-clocks the data, reduces jitter, and applies other processing.

The Stellar Strata MK2 is fully balanced from input to output, for extremely transparent, detailed sound quality and ultra-quiet operation. Its Class A preamplifier stage features PS Audio’s exclusive analog Gain Cell variable-gain volume circuitry, which eliminates the sonic degradation that can be caused by conventional volume controls.

A high-current, Class D hybrid output stage with exceptional linearity delivers 150 watts of power (into 4 ohms), to ensure that the most delicate musical details are faithfully conveyed, as well as the most complex orchestral crescendos.

Also available in black.

The PS Audio Stellar Strata MK2 offers a number of additional performance and convenience features. It’s digital filter for PCM sources allows the listener to choose between three settings, to tailor the response to personal preferences and program sources. The Strata MK2 also provides balance and phase controls (the latter for digital sources), input trim for each source, a headphone volume trim control, a USB port for potential future firmware upgrades, and a trigger output.

New Charlie Brown Goes To The Nutcracker Christmas Album

Octave Records Celebrates the Holidays
With Two New Christmas Albums — Charlie Brown Goes to The Nutcracker by Ron LeGault’s jazz quintet, and guitarist Alfredo Muro’s The Spirit of Christmas offer musical holiday cheer in stunning Pure DSD sound–
Boulder, Colorado, November, 2023 – Octave Records warmly invites everyone to celebrate the holiday spirit with two uplifting new releases: Charlie Brown Goes to The Nutcracker by the Ron LeGault quintet, and The Spirit of Christmas by internationally-renowned guitarist Alfredo Muro. Ron LeGault puts a jazz spin on the beloved Charlie Brown soundtrack music and the holiday classic The Nutcracker, while Alfredo Muro brings a heartfelt intimacy and virtuoso performances to a wide range of seasonal favorites. Both albums are recorded with extraordinary sound using Octave Records’ exclusive Pure DSD high-resolution audio process.

Pianist Ron LeGault has been performing his Charlie Brown Goes to The Nutcracker show to packed audiences at the St Julien Hotel in Boulder, Colorado for more than 10 years. “The band and I have wanted to capture the show for posterity, and Octave Records gave us the opportunity. 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. In addition, the master DSD and PCM files are available for purchase and download, including 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. (SRP: $19usd – $39usd, depending on format.)

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.
