PS Audio DirectStream DSD DAC

PS Audio DirectStream DSD DAC

Black Finish Only.

Stereophile Recommended Component 2015

Class A+ Stereophile rated DirectStream DAC converts any digital input format, such as PCM or DSD to a pure DSD stream and outputs near-perfect analog directly to your power amplifier or preamplifier.

Whatever the format, whatever the sample rate, DirectStream is a pure DSD based solution that fulfills the promise of a high-resolution analog performance standard the originators of CDs promised over 30 years ago.

Hear what’s been missing in your music for all these years. 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.
