Denon 4806 Denon 3910 DVD RMB-1095 5 Channel Amp - Will use to run Fronts and Centers SVS PB12-Ultra/2 Sub NHT VT-2 Speakers with matching center and 4 surround speakers. I have had the front and centers for 10 years and still enjoy, on problem is they are power hungry at 88dB at 6 ohms. The room is 21x21 and has a vaulted ceiling. I was also thinking of maybe a Adcom 5 Channel Amp?
