I`ll throw my two cents in…
I gotta agree with the MOTU users here. Just rock solid, and great quality. Ive used everthing from a sound blaster audigy to a huge Tascam DM 24 board and M audio cards ect….I`m back to my ol tried and true MOTU 828 MK11 . There`s newer version out now, but pretty much same idea. MOTU is really solid.
RME fireface – the must!
I’m sure Tim has made his choice already at this point, but for anyone else whose purchase is being influenced by this thread, I would invite you to look at the Metric Halo line.mhlabs.com
Their interfaces are rock solid (probably the best drivers out there), great sounding (both preamp and converters), and has a whole slew of other features that blow other interfaces away. For a pro interface that can be put put through its paces you shouldn’t really be considering a Presonus anything. MOTU is good for the composer who needs lots of ADAT returns, but the preamps are just OK. RME is not bad on stability (esp. on a PC) but again, the preamps are nothing to get excited about – they won’t ever be able to hang with any good outboard pres and a nice converter on an exposed passage.
Metric Halo is Mac only, Btw..
