Warm-up time for amps and preamps

How long does it take for your system to sound good from a cold start?
I try to keep my system on most of the time.  But occasionally I turn it off and it sounds like crap for a good half-hour to an hour.
i know there has been discussion here on the virtue of leaving tube preamps on all the time.
But my solid state amp (modified NuForce mono blocks) technician advises turning even them off occasionally.

I turn my system on about an hour before listening. Three hours later it is swinging. But I do keep it on for full weekends at times. I have found in my case my solid state amp and ancilarys improve in sound up to the next day after turn on.
I know, that is what I was thinking to.
