Majik:
As long as the Denon is in a well ventilated area you should be alright . If it's inside a cabinet w/ poor ventilation, take it out and place it on the floor or at the top of the cabinet ... you get the idea. If it start to get very hot to the touch, put a fan directly to it and it should be ok.
