That is strange, b/c I thought musicians favored the Mac environment, so I figure they would have given more attention to that context. My Sonica hasn't given me any issues on my XP system.
Lots of good DACs in the $300-$500 range--stuff changes so fast that you can pick up state-of-the-art digital gear from a couple years ago for peanuts. I like Theta, and picked up my Pro Basic III for about $500... I used to run it with a Chroma, which also sounded OK, but a bit thin. I'd stay away from the Progeny.
