Powering off vs leaving on


A friend was trying to convince me that switching my components on and off many times a day is actually worse than leaving them on. Considering the heat put out by a power amp, my instinct says power off. Am I shortening the life by doing this?

Do a thread search on this subect in the archives, it's been discussed at great length many times.
If you amp can't run at idle without overheating, consider a different amp! There are many well made amps on the market. If you worried about Air conditioning bills, that's another thing and a valid concern.

You do not mention whether this is tube or solidstate gear.
