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'm learning from this post, so will just add to @brownsf question:

If solid state gear is left on, is it best to disengage the speakers (either with a speaker switch button or with a mute button)? If there's an electrical hiccup (not a storm) it might protect the speakers... 

Is that a real consideration or am this a worry about nothing?
