Leave solid state amps on? Or turn off everytime?

Forget the Ecomentalists on this one...leave it on.

Recycle every bottle, can, and scrap of paper. Turn off the lights and replace incandescent bulbs with compact fluorescents. Tighten the faucets. Turn off the AC and open the windows. Trade in your SUV for a hybrid. Practice enlightened environmental stewardship -- and, as a reward for your higher consciousness, enjoy the music from the system that you leave ON all the time (except when you hear of an imminent thunderstorm!).

I will raise this point again, partly as I don't know the answer. Ask a fireman in the UK the commonest cause of house fires, it is TV's left on standby. In theory then, electrical equipment on standby, is a fire risk. I have never heard of a fire from this cause, has anyone else?
As an aside, I am not convinced that most equipment takes more than half an hour to get to optimum performance, at least mine does'nt.

Yes, but if you only have time for one album or CD, then you're screwed.
