Amp On or Off?

It being a solid state amp I would just leave it on. They say it will be less stresful on the internal components; plus it isn't very expensive. My old Bryston 4B-ST only cost approx. $7.00 a month to leave on. Best, Charlie

Off when not in use. Ask you amp's designer if it sounds different, in their experience, after it has been on a while. My designer said turn it off, but not tell anyone, if I wanted to stay in the "club." I do not appreciate in difference in sound, either.

Bravo to Elizabeth for clarity.
There is compromise available. I have a Rowland which goes into standby when the 'Mute" button is pressed. In this position it stays on but only uses as much juice as a 100 watt light bulb. Surely other manufacturers offer this feature. Shop around.
The amp stays warm and the bill stays small. Everybody wins.

This has been covered many times in the archives. There are some threads that contain various explanations / points of view as to why some of us feel the way that we do. I would suggest taking a look at those answers, digesting that info and then doing some simple testing for yourself. For your convenience, here's one covering Class A amps, but most of the info can be carried over to high bias AB amps also. Sean
