I think the 3900 is pretty well designed and runs cooler than my RX-V2700 did. Yes, it's warm. But that seems to happen when you include as many ASICs as it includes.
It's amp design is pretty standard, so I don't think that's the reason for it running warm.
As for more integrated, I am not sure how. Short of being able to use a single DSP, eliminating some chips needed to support the way it's zones work, and replacing the discrete amps with chips, I don't see how it could integrate too much more when compared to other designs I have seen.
Ok, they could use a single HDMI receiver chip, but I think they are a pretty recent thing, and the new Yamaha models do use a single four channel HDMI receiver chip. Perhaps Yamaha did not have a source for them they liked when working on the 3900 design.
