@ Judsondickie,
Now that you have defined what you are looking for, pass that detail along to someone at Ohm and ask specifically what some of the pairings they used when they went to a show. Dig for info. Find the amp that has proven to be a good pairing, then save up and buy one new. I went so far in my search as to look up show records that gave system details of rooms. I'd be surprised if it doesn't sound better with what you have, OHM W did the NY Audio Show in 2017 with a simple Outlaw RR2160 Receiver. Punch above your weight on your amp, and take that out of the equation for the next 10 years. Cheers.
