In preparation for tomorrow's install, I'm rearranging my entertainment center a bit. My old Tivo (Sony SAT-T60 which is leaving) was on top of my Denon receiver sitting on spacers that put it about 2" above (the entire top of the receiver has ventilation holes). But this still put a lot of heat onto the Tivo (can't complain though since it's been there for 5 years!). But from what I've read, I'm thinking the 722 probably runs hotter than the Tivo. So I was wondering if it was ok to put the 722 UNDER the receiver. The Denon receiver is pretty heavy and I didn't know how stout the 722 is or I should simply put it someplace else away from the receiver. In either case, I'll put a usb fan on the side of the 722.
