Transistors operating characteristics change with temperature.

Presumably the device was optimized and measured at steady-state on, because if you're in a lab you have to keep it on.

The manual on my PS Audio C-100 says to keep it on.

Generally with it and my previous transistor amplifier I noticed a break-in coming from a cold period for about 15 minutes.

No doubt about that, but I actually like that. When you go to a live show the first song is rarely the best, but the sound improves as it goes on, they warm up, you warm up to them etc... so I don't mind the stereo duplicating that.

Besides, if you start at the top there's no place to go :^ )

It's all about the music...

  Wind & brass instruments are always flat when cold too.
  
  (speed of sound changes enough with temperature to notice).
on and off (when off is still on and on is essentially off) - wazoo 11:00:33 09/20/10 (0)
Besides, when there is no signal being fed through a class D amp, it is pretty much as 'off' as my Pass amp is when I turn it 'off' via the front panel switch - the Pass isn't really off unless the breaker in back is switched off. I have a Bel Canto class D amp in another system, and its only switch is on the back - the recommendation is to just leave it on (which I do). I usually let the Pass warm up for a half hour before listening - warm up and break in are two different phenomenons.
