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.

The PS Audio Stellar Strata MK2 integrated amplifier is currently available in a choice of silver or black finish at a US manufacturer’s suggested retail price of $3,499 usd/ $4,727 cad. Only available via official dealers near you. For the Silo, Frank Doris.
