I have a 622 receiver that works fine, but I have to leave the cabinet door propped open because the thing puts out a tremendous amount of heat even when it is turned off. This cabinet has a stack of stuff in it, including a large receiver, and I've never had to prop the door open before, even when I was using the receiver (which I do not use with the 622). I'd love to just turn off the 622 at the power strip when I'm not watching TV because I know it must use more electricity than the refrigerator, but I understand that's a no-no. The unit works fine, I can hear the fan, it's the ridiculously high amount of heat generated that I find unconsionable, and it annoys me to have to keep the door propped open after I designed a well-functioning cabinet to start with. I dislike this one feature of the receiver enough to replace it, and one of the remote controls has worn out, giving me another excuse. If the 722 is a lot better on heat generated when the unit is turned "off," I'll replace it with a 722. Otherwise, I'll replace the remote and keep waiting. Or, should I just turn the thing off when I'm not watching TV and let it natter at me about having to update the program information? Or, am am I missing something that would reduce the standby power draw and heat output? Thank you for your advice.
