I just wanted say this is a great forum. It has helped me alot in setting up a budget HT. Anyway you probably guessed from the title that I have questions regarding heat. I have an Onkyo 573 receiver and a Sony DVD player sitting on top of it. My components are in a tv stand with shelves and this seemed like the best way to do things. I have the DVR on the top shelf and storage for cd's, dvd's and movies on the bottom. I have noticed that the Onkyo runs pretty hot. The dvd player is probably contributing to the heat also. Anyway I really don't want to change the layout unless neccessary. Does anybody know of maybe some riser feet I could put on the dvd player to raise it up a little? Think this would be enough. So far I have had no problems but I am thinking of longevity.
