Followup to my thread here: http://forums.macrumors.com/showthread.php?p=9567899 Now I'm looking for an external sound card for my Mac. I have a 2007 Macbook Pro but will be upgrading to a new model sometime soon (so an ExpressCard is not an option.) Firewire preferred, although if a USB sound card works well, than that's fine too. Does anybody know of any? All I can find at the moment is the Griffin Firewave. Any experiences with it? From what I can tell, it has been discontinued. EDIT: Also found the Creative Sound Blaster X-FI 5.1 USB, but I can't see any Mac support.
