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.

There is absolutely no reason why running without input signal would be bad for any class D amp.  This strange advice was given by NuForce technician?  Are they still in business?

I believe the above rests on a misconception; it is advised by NuForce not to turn on their switching amps without speaker load - that is, with the speakers disconnected. I imagine that's what's referred to?
