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 turn both my SS Pre & Amp off. If that is what you decide to do then this is what I found out here. Laughing Our Faces Off. This refers to the Amp, L & O = Last ON
F & O = First Off
This made sense to me as my last system, Infinity Kappa 8's with an Adcom 555II amp. This set up for 15 years did the same thing every time when turning off in this way with the volume turned down all the way down. For 15 or so seconds the speakers had a popping noise, then I turned the Pre off.
