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.

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.
