Yeah, for some reasons my brain won't allow me to buy a receiver either.
Even if all I need are HDMI switching, Internet Radio, HD Radio, & Processors for Satellite HDTV, I will end up buying a Denon AVP Processor, not a receiver.
But I think if you are using the receiver just for the processor & preamp section, it should be okay. If you are not using the amp section, that won't generate too much heat, will it?
