Stupid question of the day: Should I leave Amp on?

Here's a wrinkle - my amp is in "standby" until it's switched to full power. Is standby the same as full power?

Ideally, standby leaves the primary gain stage(s) powered up so your capacitors stay nice and juicy and ready to go.
The final, power consuming stage is switched off.

There are a few amps whose mfg'erers recommend leaving the amp on at all times. The Sim-Audio Moon W-5 could actually take a full 3 days to warm up.

But in my limited experience it seems that the majority of amps only require between 30 minutes and a few hours to warm up.

For sake of fire and/or lightning, I prefer to shut it off every night and depending on the season, even unplug things.

-IMO

Dweller: What "experts" are you speaking for? While i'm no expert on anything other than running my mouth, in my opinion, Class A or very rich AB amps benefit the most from constant power. This is primarily due to the wide temperature swing and stabilization that takes place when cycling the amp off and on. Lower bias designs with less of a temperature variance tend to show reduced benefits from constant power.

One can find quite a few threads on this subject in the archives. From what i can recall, every single person that has posted a response about this subject has experienced sonic gains by leaving their high bias amps on 24/7. In most instances, the amps reach their plateau after appr 72 hours of being powered up non-stop. Sean

Not a stupid question at all - we're all here to learn. My gear stays on unless I am away from home for an extended period, or there is a thunderstorm - in either case it gets turned off and unplugged. I agree with Sean; most of the equipment I have owned during the last 15 years needs a couple of days to get spun up.
