I haven't looked into the UMC-1 lately, have you?
What is everyone saying about the UMC-1 in terms of software these days?
I just looked at the measurements on the UMC-1, and they looked great, so the hardware is very good.
As long as the software is ironed out, I think it may still be the best thing with your other Emotiva amps!
Edit: Nope, I just checked the UMC-1 thread, and Majorloser is still having bug issues on the UMC-1. Too bad.
