The Absolute Sound Review
Easily the best DAC I've ever heard in my system

 

"DirectStream's easily the best DAC I've ever heard in my system, making digitally-recorded music sound better than I've ever heard it."

 

Audiophilia Review
PS Audio achieves the impossible

"The DS is a game changer; I think it has caused the ‘war' between DSD and PCM to be on hold or mute for most of us, and above all hold your horses before buying expensive high-resolution PCM files or DSD. That alone is a major accomplishment."

6 Moons Review
The best way we've yet encountered to turn digital into music

"But what happened now was beyond our expectations. Maybe we had been lulled into a bit of been-there-done-that reviewer fatigue but the DirectStream's handling of this CD became a rude wakeup call and put us back on edge to eat crow. Damn, the performances of the various groups and soloists were so real and at such dynamic range, it was hard to believe that the source material was a simple 16/44.1 Redbook CD."

AudioStream Review
There was an amazing sense of purity to the DirectStream's way with music as if everything and anything extraneous had been stripped away.

"Even at low listening levels, music retained its character with no sense of the sound washing out. For those people looking for a direct-to-amp DAC/Digital Preamp, consider the DirectStream a solid contender."

Stereo Times Review
the PS Audio DirectStream is the most musically and technically capable device of any type that I've ever had the pleasure to evaluate

"After listening to the PS Audio PerfectWave DirectStream DAC for the past few months it is my opinion that DirectStream represents a new benchmark in audio reproduction. Notice that I didn't say "digital audio reproduction." In other words, in my view the PS Audio DirectStream is the most musically and technically capable device of any type that I've ever had the pleasure to evaluate. My heartfelt congratulations go out to Paul McGowan, Ted Smith, and PS Audio's excellent design team for making DirectStream a reality for those of us who truly love our music."

Positive Feedback Review
this bloody DAC, DSD to the fore, is a real killer. Flat-out, stone-cold, and damn-straight

 "This is a brilliant design, with exceptional execution, and paradigm-setting sound.

I can tell you, this bloody DAC, DSD to the fore, is a real killer. Flat-out, stone-cold, and damn-straight.

It has been a while since 2008, but now I have to say that the DirectStream DAC is the first real rival to Playback Designs that I've heard. It goes right to the top of my heap of DSD DACs, right next door to the PD Series-3. The envelope for the audio arts has moved out yet again. To tell you the truth, I couldn't be more pleased! This is good for music, for our recordings, and for us all.

And that is the highest compliment that I can pay to PS Audio's breakthrough product...."

PartTimeAudiophile.com review

"...Performance is on par with some of the very best “traditional” designs on the market, and with its potential for endless upgradability, the DirectStream is revolutionary.
Highly recommended."
