eqipment on 24/7?

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

I leave my ss amp on standby 24/7. My tube preamp off. And my Cdp off. 

my Lumin T2 is left on 24/7, in standby state when not listening.
