eqipment on 24/7?

Depends. If you want it to sound good then leave it on. If you don't care then turn it off.

I leave my entire system on 24/7.  That way it is always ready to perform when I want to listen.  And yes, I have 5 tubes in my system and they remain quiet and musical.  Don't over think it!  And if doing so would compromise the tubes' lifespan, so what?  Great tubes are available at very reasonable prices these days.😀👂🏻

I leave all my solid state on 24/7, the amp is in stand by. Pre Amp and Disc. player on all the time. Unless i am out of town then they are all unplugged from the wall
