This update does live up to its name
This update does live up to its name. Right from the initial installation it was an huge improvement. Any performance increases after break in will be frosting on the cake.
Just when I cannot imagine the MK2 can sound any better...
This DAC is an excavator. It digs details out of....
- Iwin 1949
First listen on MKII for about 20min. Musically it's unbelievable.
- Brian Fitterman
Striking out of the box and better on every level
it is superior to DS1 in every way
- D Chang
You would have to pry this MKII from my cold dark hands to let this thing go
I sent the MKI back to PS Audio immediately
Amazing soundstage that is almost unbelievable!
Better than any digital has ever sounded in my system, ever!
The DAC MK II. Is an amazing improvement
I can't believe how much more came out of regular CDs
Much improved sonics
- R Schulte
On the fence?
- V Kennedy
Smokes my older DAC
The MKII is bringing out nuances in the music that the MKI is just incapable of
They sounded so good!
- D Chang
It's all there!
- V Kennedy
No idea how much better
- MS Aladino
Can't believe what I am hearing
I find the MK2 very dynamic and expressive
The MK2 smokes it
Everything is better!
- Mo Burns
The sound is amazing!
It sounded glorious!
Almost jumped out of my socks
- Ken Eis
I am listening to music again
You're in for a treat!
- Mike Pueblo
For sure the DirectStream DAC MK2 reflects the people at PS Audio and especially Ted Smith, who writes the firmware/software that has a major role in how the DirectStream DAC MK2 sounds. Of which, sounds neither bright, dull, rolled off, hyped, lean... sounds like what we want our music to sound like. Wait... come to think of it, the DirectStream DAC MK2 sounds like Ted; humble, honest, and truthful, all the while being playful and fun. Full of color and joy.... Read More
The same size as its well-regarded predecessor, the MK2 processor replaces the rectangular, four-color touchscreen with a smaller display with a Mute/Menu button to its left and a blue-illuminated five-button controller to its right. However, it still upsamples PCM data to 30-bit words, now sampled at 2× the original's 28.224MHz... Read More
