Wyred 4 Sound Dac1 vs. Dac2

Like to follow this myself.Walter is pretty straight shooter.I asked him briefly (he was at show and had limited time) about this verus the PS unit he sells for much more and he was pretty sold the $$$ value of Wyred but if you needed some of features PS had (major differences).I asked because he a really good deal on PS.If I go SS a Wyred stack seems form all reviews to have a real value (though with amps Walter admitted highs werea bit soft).But I would like to read if anybody had A/B'd them myself.

2bgeorge's response was not entirely accurate. The w4s DAC1 can play high res files, but the USB, and USB only, is limited to 24/96 (and is not asynchronous USB interface, which the DAC2 has).

As I've mentioned in the thread I started (Wyred 4 Sound DAC1 or DAC2?), the built-in digital domain volume control and async USB DAC2 has over DAC1 make a world of difference if one has only digital sources.
I cannot recommend the DAC2 enough for a computer-based system, using the asynchronous USB!
I now have it paired with W4S ST-500 power amp, connected via AudioQuest Columbia XLR.
This combo delivers superb sound at an incredibly low price point for what it offers.

Roscoeiii- your comment about the DAC1 not having Async USB seems really important. This is what Gordon Rankin and Ayre having been touting as the major source of improvement. So unless the DAC chip itself is impervious to jitter, it seems as though the async USB interface is a must and therefore rules out the DAC1 as a competitive option.

I am curious if anyone has really compared this particular piece. Since I am considering this as a cost effective alternative to the Ayre QB-, I would love to hear some comments. (I run J-River on Windows 7)

If USB is not your primary source,
If you don't care about the remote,
Then the dac1 with the $50 supercaps upgrade (ask when you order) is equivalent to the dac2.
