Thanks to all for the input. I will definitely try to address the thermal issue when I get home tonight. If that fails and everything else checks out, what receiver would be a good solution? I have a 14 year old Denon DRA-325 (50 wpc) in the garage that I will try next, but if I have to buy one I'm thinking of going with Harman Kardon or is there a better solution? Comments? Thoughts?
