I recently purchased an IntEgra DTR 7.1 as my "upstairs" home theater component. (My home theater room is run by the Denon 5800). First of all, all I can say is I'm darn impressed by the sound quality of this thing. It's currently hooked up to my computer's DVD drive which passes RAW data signals, so I can can both DTS and Dolby. A couple of things I've noticed is: a) it runs quite warm (compared to the Denon). But has ample space above for venting. b) it "clicks" when I switch DSP modes. Is this normal?
