"It seems I have to continue putting up with listen to music late at night after giving the system most of the evening to warm up."
Spatine - Can you hear it improving over time. Would you know if amplifier was ON for one or three hours? If you cannot tell then don't listen to somebody's recommendations.
You made excellent point about power outage and surge. I use surge protector but still turn off the switch while not at home and unplug my gear during thunderstorm or long absence. Surge protector works for small spikes but is useless for direct lightning hit. My insurance agent told me that stereo equipment is always insured independently of value (One doesn't need special insurance) but it's a little hard to believe.
My amp is class D and uses about 10W idling but I still turn it OFF - I don't see (should I say "hear") reason not to. In case of class A amps electric bills should be one more argument - unless one can really hear big difference over time and is willing to pay for it.
How about blind test - you come home from work and find your gear ON. You have to guess how many hours it was ON. This would perhaps tell us what is real and what is placebo effect.
