Just bought 65inch plat-plus mits need a receiver under $500. I heard a Denon sounds great any tips? Radio Shack has an RCA a-v receiver with 100X5 watts, Dobly Pro Logic II, Dolby Digtal, DTS, 5.1 channel, Virtual Rear Center Channel, 6 DSP Modes and so on. I can purchase it new for less than $200.00 with my wife's corporate discount. Why is this RCA so much cheaper than the high end brand names like Denon and so forth?
