About a year ago when I purchased my first HT I did as much research as I could. During my research I noticed internal design "flaws" from one brand to another. I talked to a non commissioned person at Best buy. He directed me away from all of there recievers that the sell believe it or not. He pulled out a Sony and explained to my why he didn't recommend them. I ended up going with a Denon reciever. Now this is what I was told/learned during my research: If you look through the vents on the top of the reciever you can see all the chips, etc.. on the Sony's and Yahmahas amplifier and chips and right next to each other. If you look through the top of Denon, Harmon Kardon the chips and amp are seperated by the heatsink. This design is superior because it doesn't allow the reciever to get too hot over time. The amp on the Sony will heat up and after a few hours the quality of the sound will not be as good and you can hear crackle in the speakers some times. I started looking at the brands seemed, Denon, H/K, Technics, Onkyo and the ones that weren't were pioneer, Sony, Yahmaha. Anyone got any opinions on this?
