Ah right, didn't know the Firewave was bus-powered. And so can the M-Audio. That makes it easy I guess. Thanks 😀
I'm not convinced the Firewave is much better than the new-gen MB/MBP/MPs built-in sound (apart from the fact it gives analog 5.1) but I'll have to give it a try as wellas the M-Audio. If anyone can think of a higher-end one that'll be great too. Thanks
