solid state gear- leave on?

I leave my ss amp on in stand by 24/7 unless i go way for more than 24 hours then its unplugged from the wall. My preamp and disc player are on 24/ 7 with their screens turned off unless i am gone again for more than 24 hours.

I have always left SS amps on 24/7 and they have lasted 20 years or more!

I listen 3 or more hours each day, and do not want to listen to poor sound quality throughout the warmup phase.

YMMV

I was perhaps too harsh when I posted previously that leaving your amps on all of the time is simply wasteful…I do have my RELs in standby so that’s a watt or two down the drain, but since I actually feel that saving the weather systems on this planet is utterly a lost cause, and the perceived benefits of warmed up items is important to many, I say leave everything on. Seriously…it no longer matters…your car engine suffers most of wear during the warmup so hey….let it run…why not?..you can afford it…leave the refrigerator open while cooking to help cool the kitchen as the ambient light provided is adorable. Nobody wants poor sound quality, and if your children get their ankles wet visiting Venice, tell ’em to quit whining. 20 years of wasted electricity maybe could power a small third world village but so what? They likely hate us anyway. Turn it on, leave it on, it doesn’t matter.

Many amps are made to be in stand by then i would leave it on 24/7.

Many years ago I worked at a professional recording studio where they left their (all solid state) equipment on 24/7.  When I asked the most senior engineer about that, he said it was because there were way too many things to power "on" in the morning and to him, the extra electricity didn't cost him enough to sweat it.

I do not leave my equipment "on" all the time, all digital/solid state.  Yes, I do hear it sound a little better as it's on for a while, but after 20-30 minutes, it seems to sound as good as it will get.  My equipment doesn't get hot at all, it's all barely warm to the touch (except for my DAC).
