Ok, so my M-Audio Profire 2626 is no longer getting driver updates and is no longer compatible with the current version of OSX. I haven't updated, but I'd like to be able to at some point. I've had this interface since 2009, it's served me well, but I'd like to upgrade to something a little higher end, and it'll be a hell of an upgrade for my dad. Let's say a budget of around $2k, +/1.
MDV has been positively raving about his RME Fireface UFX, so that's a strong contender. Anything else I should look at?
Also, at some point, I'll be looking to grab a few external preamps (especially if I grab the RME, which has four pres). I haven't given myself a budget yet, and I'm going back and forth between grabbing something like the ART Pro MPA II to grab a 2ch pre for relatively short money that will hopefully still get use 5-10 years down the road, or just dropping a comparable amount of cash on something quite a bit nicer - Universal Audio does some REALLY nice looking 2ch and 4ch stuff, but that's getting into a pretty serious amount of money.
