+1 for Denon... I've driven it for hours on end and it's only warm, never hot.

Compare that to my PS3 after an hour of watching a movie and the top of the 3808 feels like an Arctic tundra in comparison (not that the PS3 is a good measuring stick, but suffice it to say, the Denon does not run overly hot)
