Hi mdrew,
My condolences on your dead 7200, but I'm glad it's still under warranty. I'd advise you not to go with B/A. It's too new, there's no long-term reliability stuff on the brand, and if it's based on Sherwood, the latter has a dubious reliability record.
I had an Onkyo blow its output section some years ago. It was the first failure I'd had of a amp/receiver in 20 years or so, and I was annoyed. Then I found out they had had manufacturing problems, which I hope are solved.
Since you have M80s, there's always Denon, which will drive them. Think about an Outlaw preamp and the multichannel power amp as well. I''d avoid Yamaha if you are running a number of low impedances like the M80s and the M22s in parallel.
Regards,
