I know that. My point was that even a single ADAT port is probably more than I'll need (I could probably make do with less than eight channels), so a card with three or four ports is kind of silly for me. I could justify getting an ADAT card and an ADAT mic preamp (like Behringer's ADA8000), but not if I'm spending $500 on three times that number of inputs I'll need. That's exactly what I was trying to find out. The only ones I am aware of are the 9652 and the 9632, both of which sport multiple ADAT inputs. I'll scout a bit more on RME's stuff. Is it safe to assume that all RME's PCI cards are supported? I've only heard of the 9652 being used with Linux. Zachary Klein
