On or Off

I have a Pass XP-22 preamp and I would like to know if it should stay on when not in use, it has a switch on the back but I always have it on; Being class A the temperature is high, can this shorten the useful life in the long term?

I reently bought a used Pass Labs XP-17 phono preamp.  It too only has an on/off switch on the back.  I called Pass Labs and was told to leave it on all the time.

I leave my Pass pre and Ayre phono on but switch off the Pass amp but try to give it at least 30 minutes warmup.

Pass always sounds better off to me.

Just a joke people.  Commentary about readers who only read the headline and not the OP.

You have an on/off switch? Wow! My XP-15 phono stage doesn't. The only way to turn it off is to unplug it. I'm guessing it's meant to be left on.
