Hi Andrei,
Pretty cool, I was also thinking of designing a DAC with TI's USB and DAC chips.
Have you considered having a balanced outputs to a preamp plus a headphone out?
I'd like to design a similar circuit with the Pass D1 I/V stage in balanced mode. One nice aspect of the Pass I/V is the way Neson incorporated a volume control.

Very neat. I would add a few things: You should put a volume pot before the intersil buffers. Digital attenuation via the computer degrades sound quality. Second, those buffers have a tendancy toward dc offset without a 1K resistor on the input. I am working on a similar thing but with a tda1543 and all usb power: http://headwize.com/ubb/showpage.php?fnum=3&tid=6233
