So here's my pickle. I am currently running my Apple Airport Express through my DAC1 using the AE's optical out. However, if I wanted to use a USB DAC, I would need a converter for the SPDIF--->USB conversion, correct? I'm aware that such things exist, but I'm wondering:
a) Do they actually work well in practice, and
Would such a converter work coming off the AE instead of directly out of a PC? In other words, most of the converters I have come across tend to have a PC in the mix, which indicates to me that maybe there's a driver issue. But I don't know shit, so help me out.
