DirectStream Junior

An affordable state of the art DAC

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 twenty 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.

Now, full MQA, Tidal (including Masters), Spotify, Qobuz, VTuner and Roon ready.

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, are unwilling to compromise sound quality, and want to hear what’s been missing on your discs, then this DAC is right for you.
