I'm not completely sure, but I think it's an improvement on the software that chipmaker Cirrus has available for those processors/receivers that use their DSP chips. I have a UMC-200, but I go the manual route by using the 11 band P-EQ, along with REW and a miniDSP UMIK-1 for measurements...
Here's a new offering from Emotiva, it's pretty much a UMC-200 with a power amplifier. It's two very important features in my opinion are the full 7.1 pre-amp outputs and the P-EQ.

My experience is Oppo is quite reasonable when sending in a unit for repair. Can't hurt to call their customer service and see what they can do for you. I still have a BDP-83 going strong and while it's not the fastest to load, it still plays blu-rays every bit as my BDP-93.

Used Emotiva is a really good option as well as it has a transferable warranty. You could also call Emotiva and ask if they have any B-Stock of the model(s) you are interested in and their 5 year warranty also applies.

You need power amps to run with the Audio Control Bijou. Pre-amp outputs into the Bijou, then the outputs from the Bijou out to the power amps. Actually if the Audio Control Bijou is in good condition, you can get at least $400 for it, and I mean at the least, on eBay. It goes for $1000 new...
