Wyred DAC-2 vs. PS Audio PWave

Would love to hear the progression on the comparison between the PS and the Wyred2 is. I am building another system thinking about what to do maybe use this dac. What Transports are people using?

I'm using a Cambridge 550C as a transport for my DAC-2.

I have been using a Sonos via coax into my Dac2. But I also tested the waters with a Mac via the asynchronous USB. What's really exiting, though, is to use the the memory player feature in Pure Music with USB out. I'm trying to build a system that will let me do that routinely.

Slanski-
How did the Sonos compare with the async USB output from your Mac? Also, were you using the DAC2's internal async USB input or some other solution (like a HiFace, etc.)?

I used the USB out of the Mac and directly into the DAC2. The sound of the USB was somewhat better than the Sonos, but the difference wasn't huge. Maybe it has to do with the way the ESS chip copes with jitter, which is the Sonos' weak point. In any event, the big advantage to using the Mac/USB is that it allows me to multiply the benefits of 1) asynchronous data, 2) high resolution files, and 3) Pure Music's memory player (with iTunes).
