Thanks Lawa - my preamp has analog outs only.
I really like the presonus gear, but to convert to line in signal I'll need to run the preamp out thru a di and I'm not too keen on that. Focusrite also looks great and in keeping with your comments, I read a lot of good stuff about their products. Plus, they offer the line level inputs I want/need.
On focusrite's website they have drivers for Windows 8, but they don't specify 64 bit like they do for all of the other OS. Trying to find that out before I bag one of these.
