How hot do a pair of Pass Labs X600 amps run ?



According to Pass they idle at 600 watts.
I'm not an engineer, but my research translates
600W to 4,000 BTU. What have owners experienced?
Thanks.

Ah! and thus the 200 fully class A watts XA housed in the formidable X - 1000 chasis. This should give pause to owners of the trim mega watt "class A" amps that abound.
That idle figure gives about a 150 watts of class A continuously. I have a pair running at this moment as I write. They are breathing sublime life into the toughest speaker load known to audio. The blue back lit dial is resting quietly in it's customary ten o'clock idle setting while the music flows at 70 to 80 hertz, my comfort range.
The 600 white papers say 150 watts. They act like there is more. The heat sinks are huge, and do get good and hot. Each amp weighs in at 150#.
In a house with 62 light bulbs, all of which are left on too much due to kids, the initial extra cost of the monos was absorbed without raising WAF ire, and that is a good thing.

All of the 600 watts are lost to heat when not running. I suppose, at peak 1800 watts, that too eventually winds up as heat. The speakers are huge radiators.
