It's true that many PCI soundcards have better capabilities than their
USB counterparts. And at certain levels (multichannel in particular),
the throughput exceeds USB 1.0 and you would need a USB 2.0 high-speed
USB sound device to match that.
However, besides the obvious portability advantage of USB devices, there
is one other interesting feature of USB audio, which is to isolate the
A/D and D/A converters outside the generally noisy computer case, and
this can provide higher audio quality than an internal PCI device. But
only the higher-end USB devices would really have that advantage. I have
used some low-end ones that were just as noisy as the first ISA
Soundblaster 1.0 (Edirol UA-1A if you must know).
