On or Off - On or Off - Audio Electronics

Great conversation, I think it about it all the time.  In my advanced age and paranoia, I turn it all off.   

I prefer my gear on all the time, but i tend to use standby which all my gear currently offers ... when I had the huge Pass Class A XA160.8 mono blocks, I called Pass, and was told there was no correlation between leaving any of their amps on 24/7 and increased repairs or lesser life expectancy...

On until it is off in the end of the day.  Off for entire vacation, completely off.  

I set up a second system because my main rig is all tube.   I needed something that if I dozed off I wouldnt have to worry about the rare chance of a failure.  

I bought a Cyrus Integrated amp.   It has a great feature , Auto Off.    After 20 min of no signal it turns itself off.    I rarely turn it off manually,  I mute of turn off the source and it takes a nap.   

Generally speaking, I turn all gear off when not in use.   Only exception is my phono pre, it has no power switch.  

Okay, you already know that tube equipment should be turned off or you will exhaust the tube life in a few short months.

Pre amps and Amps with a power button in the front (SS), turn off.

Graphic Equalizers, turn off.

AM/FM Tuners, turn off.

Tape decks, turn off.

CD Players, turn off.

Turn Tables, turn off.

Any powered speaker that doesn't have auto off, turn off.

Phone Stages- it depends.  If SS it may use MOSFET or FET technology, therefor leave it on as the FETs like to be warm to function properly.  They don't use much power in stand by mode and are very robust.  If a tube Phone Stage....turn off.

I don't think I missed anything......
