I have a Denon PMA-860, a great amp. One thing I've noticed is that the thing never gets hot. It doesn't even get warmer than ambient at low volumes. At medium volumes, it becomes just barely perceptibly warm. At high volumes, it gets modestly warm. This is driving 4 ohm Infinity RSb speakers, and as we know, Infinity(s) tend not to be very efficient speakers.
I was wondering if it would be a good idea to adjust the bias to make the amp operate more in class A, as it clearly has plenty of ability to dissipate heat.
