People who think the ADI-2 Pro EX is expensive, why not consider the Fireface UCX II audio interface instead. It costs significantly less (it's like 1 thousand euro on Thomann without tax) while offering far more functionality. You get many more I/O channels, effective 12-band EQs by onboard DSP for the output channels instead of the 5-band EQ on the ADI-2 series, real microphone preamps, MIDI I/O, and, most importantly, TotalMix support, the most flexible and robust routing matrix I've seen in the industry.
What do you lose? Louderness feature, DSD support, remote control, better analog specs, superior headphone output stage, and the black chassis. In practice, most of these don't matter. You won't hear a difference, and for most headphones the UCX II output is beyond just fine. The only thing I would personally miss is the spectrum analyzer on the front-panel display, which is very beautiful!
