Hey guys I have a question about receivers in general, and more specifically my HK 7300. After watching a movie and playing games for a few hours at decent levels it gets kinda hot. The only thing is I am not sure how hot is normal. I have it under my sony tv stand with the top shelf as high as it goes and the HK on the bottom. It has a lot of space on the sides (about half a foot, and about 4-5 inches on the top. I also took the back of the stand off for more air flow. How hot is the receiver supposed to get, and how much air flow is suffecient? Thanks guys
