I'm looking for a good USB soundcard...I have a little project I'm building and need one. I read that most don't work the way they are advertised. Like Creative has a 5.1 USB soundcard, but it doesn't actually process the sound into 5.1. I'm looking one that can...and maybe enhance the sound a little...optional, but not necessary. Money is not my concern now, I'm just need to know which one's can do it properly.
