Leave it on?

I turn everything off the second I stop listening. And thanks guys for using this an opportunity to lecture us on climate change. 

Again lets talk about nuclear and not the other other underperforming solutions.

Interesting, inrush current having an affect on cap life. That is also not any kind of spec on caps. What is a spec is time, temp and voltage. 

On tubes, they also do not like heat, or voltage spike/changes. There are devices that stop inrush current on tubes, power them up slowly. 

On switches a lot of new stuff doesn't have one. If it does have a power switch, it's not really a power switch, but a button that puts the unit in stand-by. 

My system is all plugged into a Furman, I just flick the mag breaker off when not in use. Don't use any of the switches on my gear. However, my HT system has power all the time.

Sound wise, yes, leaving it on is best. Not sure it's best for longevity. Also think what Paul is saying when using perfect power with a regen unit, there may be less of a need to power down. 

@larryi all my tube equipment have tube rectification, it's usually harder on the filament during turn on, even if tube rectification is used.

You're so very welcome. And you sound a bit touchy about the topic. I heard a couple mentions but no "lecture." Why not nuclear AND renewables? It works in many places not stuck in binary ruts. Read up and try to think a little bit.

Keep my solid state equipment on 24/7.
