It's 5-channel and 7-channel receivers where amplifier cooling becomes a huge issue with lower impedances.




Hey if im wrong about something dont be afraid to say so.

On another note i can definetly see where heat would become a problem when drivnig 7 channels. My C370 gets fairly warm, especially over the area where the pre-amp "modules" are located. If i had 5 more channels in there that thing would get cookin!
