As I've stated before, I love Marantz products but their published watts/channel data in AVRs can be misleading. If you read the specs closely, they'll state the watts/channel/8ohms but "two channels driven". You can figure that in reality, 70% of that value would be achieved with all channels driven. Rotel and NAD on the other hand publish true "all channels driven" wattage specifications. Can't go wrong with either a Rotel or NAD AVR. I've finally gone to separates and absolutely love my current arrangement which is an Integra DHC-40.2 surround sound processor and the new Rotel RMB-1555 multi-channel amp @ 120 watts/channel into 8 ohms 20hz-20khz all channels driven. If you can swing separates, go for it.
