When to Poweroff amps and preamps

I apologize if this has been asked before but I haven’t been able to find it.  What is recommended for when to turn off the power to amplifiers and preamps?  What if you’re going to be using the equipment within a day or so...power it off completely, put it on sleep if that’s available, leave it on?  What if you’re not going to use  it for a longer time...a couple of days?  A week?  Are there different recommendations for solid state and tube equipment? I’m interested in both getting the best sound and prolonging the equipment life.

I’ve never had a SS amp fail due due to on/off. Every device is unique. If you can hear a difference with yours and don’t mind paying for unused power, by all means keep them on 24/7. You better have real surge filter/suppression in series for the enivitable electrical storms.
Of course tubes have finite life spans. You gotta pay to play.
Check your stuff with a Klil A Watt.
Most "stand by" uses 90% of the kWh for a few seconds of faster play.
No audible difference with mine.
I even unplug the power sucking cable box off nightly via a timed outlet.
