UFX II is not mobile, too heavy and excessive in features for me but very important for me HP out impedance is 2 ohms.
Babyface is better - only 0.1 Ohm, but lack of features. Maybe 2 working together is ok or maybe UCX+Babyface Pro.
No other options, because UCX has perfect features set, but is HP out impedance is 30 ohms and thus not acceptable for me. I will be grateful for information on audio quality difference between.
I went from that MOTU to a BFPFS. To me, they're both audibly transparent on the output - I couldn't hear an obvious difference. Maybe someone could tell but I don't claim to have golden ears.
Not sure what kind of IR capture you want but, for basic acoustic measurements, virtually any interface is fine. Rooms have SPL deviations of 50dB, in some cases, whereas most interfaces are well under 1dB.
Everything about the BFPFS is audibly clean and the headphone output is decently loud - definitely louder than the MOTU. I know you're talking about impedance and features but I can't help you there.
Both the MOTU FW and BFP can be bus powered but I'd feel more comfortable travelling with BFP. It's got a case, after all, and less knobs that stick out and it's smaller. Less hardware I/O but enough for me.
