Leave an amp "on" permanetly

I will say that it is possible for a switch that is turned on and off will eventually give out.

Warming up does matter; but then, after 30min to 1 hour of warming up, things should settle. Leaving it for 24/7 should not be necessary.

Afterall, please do our poor planet a favour. Those mega muscle amps burn a few hundred watts when idling.

I can see how it will not harm components to turn them on and off. But I am curious about the following:

How long does it take the average solid state system to 'warm up' and sound its best?

Will it shorten their life to leave them on 24/7?

And how much electricity is used when they are on but idle?

I leave mine on all time and have for years, and I dont care about the Green movement. All the Liberal tree huggers do is just buy Carbon Credits that dont mean anything, its like going to confession....you can do whatever you want as long as somebody clears you of your "sins".

I think there might be another thing to consider: possible damage to speakers if there is a power surge or interruption, or a malfunction upstream in your system, that could send a large transient through your power amp and on to your speakers.

I am driving my Thiel CS3.6's with Rowland 201 monoblocks, which draw very little power, and which could be left on 24/7 if I wanted to. Because of this concern for transients, I always switch the amps off when I'm not listening.
