What transport does Purrin use?
I've had quite a lot of troubles with my USB experience lately too and my issues were pretty much what he describes in his post (even worse, considering that the very fact of listening to music became painful at times...).
Yet, few month ago, I was able to eliminate all the issues (don't ask me how, I wish I knew why I messed up everything 2 weeks after...!!) and I could enjoy the best sound ever heard on my setup with the built-in USB-32. So good that I was questionning the fact it could get any better than what I heard. I'm still miles aways from that time, but things improve gradually...
This was with the NFB-27.
