DirectStream Junior

A pure DSD approach to digital audio playback

Built in Boulder

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!

DirectStream Junior DAC

Product Description

Whatever the format, whatever the sample rate, DirectStream Junior (DSJ) provides a pure DSD based solution that fulfills the promise of high-resolution analog performance from digital audio. If you know the sound of music and instruments, and want to hear what’s been missing on your discs, then this DAC is right for you.

DSJ provides remarkable performance that uncovers all that buried treasure in your digital music collection. In fact, we’re confident enough to suggest you haven’t really heard what’s on your CDs and SACDs until you hear them reproduced through the DSJ. Connect DSJ to your NAS, computer, or favorite internet streaming station through its built in Bridge II, I²S through an HDMI cable to the PWT (or upcoming DirectStream Transport playing your favorite SACD), or any digital output source, and sit back and relive musical performances few have enjoyed at any price.

And now, DSJ and its built in Network Bridge are ROON Ready.

Digital Audio Review

John Darko

the DSJ, like its Father, still delivers on the three Rs: rich tonality, robust dynamics, revealing of low-level detail, textural information and spatial cues. What a winner! This is a high-end audio solution that our parents could use. Stupendous sound, fuss-free, intuitive and highly relatable.

the DSJ offers up a musical image that is rich, fluid, and full. There's a nice dimensional quality without a hint of digital flatness that plagues, well, lots of digital reproduction. There's also no sense of the overly-etched or hyper-detailed presentation that my reference Auralic Vega can lean toward. I'm not saying the Vega is overly-etched or hyper-detailed as I've enjoyed it for years, but compared to the DSJ, it does sound a tad forced; as if it's trying too hard.

Positive Feedback

Mark Pearson

I think that PS Audio hit a homerun with the DSJ. It's beautiful to look at, it's simple to use, it has all of the digital inputs a reasonable person could hope for, and it helps protect your investment by being software upgradable. I'm a fan of FPGA chips because of their functionality and how they sound. For those of you (like me) who have never enjoyed your CD collection much or your hi-rez digital files, the DSJ just might put a smile on your face like it did mine. I found that PCM recordings that I just wouldn't play before I could now play and enjoy through the DSJ. For me, that aspect is the icing on the cake, because being a DSD fan, I love how the DSJ sounds with native DSD files. If you get a chance to hear the DSJ and see and hear what it brings to the table, I think you may just be smitten too.

With their DirectStream Junior DAC, PS Audio has managed to offer the technology developed for the DirectStream “Senior” for only two-thirds the price. What makes the DSJ special isn’t merely technological, but that that technology is used in the service of outstanding sound quality to make it among the best-sounding DACs I’ve heard. The DSJ is an incredibly detailed- and wonderfully transparent-sounding component whose fluid, natural sound is musical and highly addictive. During my time with it, I enjoyed revisiting many discs and files, simply to hear how they’d sound through the DSJ. It never failed to impress. If you’re in the market for a new DAC and want topflight sound, it would be a mistake not to hear it.

Suono Italy

I'd say it’s pretty hard to do better, at least for now. The machine has all the features you should expect from a modern DAC: it’s upgradeable, and compatible with all formats; it can be used without excessive loss of quality by connecting it directly to a power amplifier; and you can use it as a network streamer. Mostly I would say it has its own well-defined personality, which is reflected in really good sound.
