Wyred 4 Sound Dac1 vs. Dac2

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.

But to make sure everyone is clear on Mizuno's post, the DAC1's USB is NOT equivalent to the DAC2's. It may be possible to pay extra to get async USB on the DAC1, and still save some money from the DAC2 if you don't need its other features. You'd have to call Wyred to find out about that. Or go with a USB to coax/BNC adaptor that is async, something like the HiFace.

The USB can be upgraded on dac1, $250,

Don't forget that the DAC-2 has HT Bypass, a huge plus for those who have a integrated HT/2 channel setup.
