Well, I've been putting it off for a long time, but I'm going to upgrade the interface this summer - maybe this week. My basic thought is the RME Fireface UFX. A few extra features that (I think) make it worth the price over the 800. For now, I'll be using it with PT9. I'll be connecting via ADAT to the Focusrite Octopre. (I'll keep using the Octopre's converter card until I've added more quality preamps.) There hasn't been that much discussion of the UFX here, but I've been sort of doing due diligence, searching around for compatibility problems or just other complaints about the UFX. Any thoughts?
