Hallo,

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.
I don't think, this is really true anymore. This was true, when there
were cables running from the sound(blaster)card to the CD-Rom drive,
which acted like a kind of antenna to collect electrical noise and
induce it into the soundcard. But modern soundcards even in the 20
Euro sphere aren't affected by electronic smog inside a computer at
all. They might have bad converters or microphone jacks, but e-smog
generally isn't much of an issue.
Good PCI cards like the many with ice1712 chips even are much cheaper
than equivalent USB boxes. So there really is little reason for using
a USB card with a stationary machine. This shouldn't stop anyone to
use one with a laptop though, in fact USB is the only affordable
solution there for most cases (that don't require a HDSP).
ciao
