I would imagine John Swenson could give you some tips on what type of USB DAC would work best so you could inquire of each company if their USB DAC fit the correct parameters. Just a guess though.
On a different note, am I the only one who thinks Ayre missed the boat by having a USB only DAC? I would have thought the QB-9 would've sold many more units if it had a coax/toslink in as well. Of course, I'm no DAC designer so I'm speaking purely from my @$$ on the subject.
