Well, in a "top" recording studio, the PC would just serve as the
control/interface to the good stuff; rackmount or discrete equipment
rather than PC sound cards. But here are some brands that offer
audiophile grade and professional recording sound cards:

M-Audio

Lynx Studio

EMU

RME

AudioTrak (prosumer rather than professional)
