That's one thing with which I have very little experience. My only experience with USB is using the Modi (using foobar and .wav rips) at home for about a month and a HRT Music Streamer II for a couple months up at work (mostly streaming MOG). I'm still a huge proponent of physical media and greatly prefer LP's, SACD's, and even regular CD's to USB/computer audio. I guess I'm just a (not yet) 30 year old dinosaur. At least I'm trying to get into it.
