PS Audio DirectStream Junior DAC

A pure DSD approach to digital audio playback

DSJ is a technological wonder that builds on the same architecture awarded Product of the Year in both Stereophile and TAS, Darko Knock-Out award, Editors’ Choice and Golden Ear awards. DSJ is an extraordinary performance instrument–handwritten and uncompromised–a pure DSD Digital to Analog Converter uncovering all the missing information long hidden in your audio library, from both PCM and DSD sources.

CD’s, high-resolution PCM, or DSD based media, are expertly upsampled to ten times DSD rate and output as pure analog directly into your amplifier or preamplifier. DSJ is one of the few, true, fully analog DSD devices, that’s setting the industry on its ear and reshaping the landscape of music and high end audio. And now, DSJ is ROON Ready!

Pure DSD done right

Introducing DirectStream Junior (DSJ), a world class DAC based on the architecture of the Stereophile and Absolute Sound’s Product Of The Year, DirectStream.

DSJ uses the same FPGA architecture and customized code as PS Audio’s DirectStream DAC, and it is designed and built by the exact same team. The idea behind the DSJ was to offer near-identical performance at a fraction of the cost. How was this accomplished? Lower cost chassis and user interface.

DSJ, like DirectStream, is hand-written, discrete, perfection based conversion that uncovers all the missing information hiding in your digital audio media for all these years. CD’s, downloads, high-resolution PCM or DSD based media are expertly upsampled in the DSJ to ten times DSD rate and output as pure analog directly into your amplifier or preamplifier. Classic PCM-based DACS, including many of today’s DACS that can also process DSD, tend to cover up some of the subtle musical details buried deep within digital audio music; a problem inherent in their architecture. DSJ solves this problem by employing a pure DSD single-bit approach for both PCM as well as DSD media. This means that your entire library of music can finally reveal all the music and subtle low level details buried deep within its core – and now, at a more affordable price than its progenitor, DirectStream.

Imagine going to a recording studio and listening to a master tape of any recording made. This is the experience DSJ affords its owners who enjoy a renewed sense of enjoyment and discovery when listening to everything in their library: CD’s, downloads, DSD.

This worked straight from the box, as it already had the latest firmware installed. I feed it direct into my ATC P2 power amp. No need for a pre-amp! Very clear sound reproduction. I definitely can hear more extracted from each track as the manufacturers claim. Roon ready too. Firmware can be upgraded from PS Audio's website. Good community forum there too.
