Leave solid state amps on? Or turn off everytime?

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.

How do you explain refrigerators, which are either in standby or running 24/7, and which use more power than a TV?

I don't buy the argument that TV's left in standby are the commonest cause of house fires. Rather, I suspect it's TV viewers who fall asleep while smoking that may be the commonest cause of house fires.

Bel Canto if they are digital is no problem on... But then again turning them on 2 hours before helps too if you want them off most of the time.

Turning a ss power amp 24/7 may not affect the life of any electronic components?
