Hi everyone, I've got a golden opportunity to score some home theater stuff, and I was looking at some of the Harman Kardon receivers. I've heard nothing but good things about them, but I noticed that some have no more than 50W/channel and the AVR 520 is only 85W/channel. For such a high price tag, what makes Harman Kardon so good? I know power isn't everything, but what is it that makes Harman Kardon so respected? Any info/advice is welcome. Thanks in advance!
