What USB soundcard (model/manufacturer)? Because most cards, like the Asus Xonar U3 are very weak compared to their internal/PCI brothers, mostly limited to 16bit/48Hz, unlike an entry level Xonar DS that does 24bit/196Hz, and has better DACs. Only a handful of external USB DACs can be considered "audiophile" grade, and internal soundcards like the mid to high end range of the Asus Xonar line.
