Giro,
I run (4) m80ti (1) Vp150 and (4) Qs8 on my Denon 3803 and have for the last 8 mo. I have had no problems with heating up the receiver or any othe problems. In the beginning I was concerned from all I heard about 4 OHM Imp but I ran calibrated temps on the receiver and the temp never rose above 118 degrees even on a hot California day. I wouldn't worry this is a fantastic system m80 and Denon 3803.
Good Luck,
Lee
