Leave it on?

@mylogic  many thousands of products are made from oil, how much do you think all those products will cost if we aren't using carbon fuels? 

@invalid 

As l said, oil is okay with no other choices. 
 

Your last question to me in unanswerable.

I never turn off my accuphase integrated or my aurender streamer, as recommended by the manufacturer. The only piece I turn off is my Manley tube preamp to preserve the rather expensive tubes. I leave my simaudio amp in stand by all the time. I’ve been told the constant cycling is bad for the power switch and the capacitors. I’ve never had any problems with my equipment. 

Me leaving my amp on 24/7 (which I do) will not destroy the planet any more than turning it off will save it. 

@mitch2 ,

Do you hear any appreciable difference with your thermal magnetic switches in?
