Seeking hot running amps


Which poweramps run hot? I am looking for a hot running amp to warm my room in the winter. I have heard of Krell, pass, threshold.

The hottest amp I've had was a Pass Aleph 5. You could not keep your hand on it very long type of hot.
My Lamm M 1.2 reference are just warm enough to roast a mashmellow on during a frosty morning. I would look at these. I may be exagerating the heat a little but you get the idea.
The Gryphon A class amps such as Antileon signature will definitly heat the room and sound better than most amplifiers,down side is the weighr the stereo version weighs about 220lbs.
tubes are welcome. my audio research sp16 (6 tubes) emits a little heat. I want to heat and warm the room at the same time.
