Since I do not like to suffer through a one hour warmup then "Good" sound after playing for a half hour, to finally get "Best" sound quality with my Pass XA30.5, I leave it fully on, 24/7/365.
It costs me $15/mo in Minnesota. 200 watts continuous.
I also worry about temperature cycling the output transistors and the effect on reliability.
The XA30.5 does not give off that much heat. Not any more than my old GAS Son of Ampzilla that did not have an on-off switch, that I ran 24/7/365, for 20 years, without any problems!
The "big" Pass Labs or other Class A amps would be expensive to run continuously, and if I owned one I would put it in standby when not in use. And as a result "suffer" through "less" than perfect sound quality, during warmup.
I have QA, test, and reliability experience, in military and medical electronics.
