I am having a difficult time deciding on these 2 recievers. I have a dedicated home theater which includes:Infocus 7205, Denon avr3600dts (the need for upgrade) denon dvm3700(5 disc dvd not progressive scan) with polk audio front rt1000p, csi5, fxi3, sub rm404. Room size is 14x25. The reviews I have read have been very favorable for both. How do I decide???
