Ah, but you are still 2 channels short, that 48XX has 7 channels, I know not many use them, but then you are able to run a second zone off these unused amps, this is where the convenience and feature packages come into the bang for buck formula of avr's vs seperates. So if a person wanted that second zone from a seperate system you now have to look for another 2 channel amp and the price of seperates goes up and is no longer as economical.
