I second or is that third, both John's and Michael's suggestions.

Dean('grunt' on the forum) has the Onkyo 3007 and it appears to run the M80s very easily and I also have the 3808 and it has worked great for me. I wonder if the Dealer you went through would be willing to give you a new or refurbed 4310 in exchange (yours seems to be a lemon), this way you wouldn't be out of an avr during the repair time. It wouldn't hurt to ask.
