Class A Amp owners, Whats your power bill?

In Las Vegas: My power company wants to raise rates because we (their customers) have cut back our usage so much that they can't afford to pay their employees.

Onemug: I attended a demo (Evanston, Ill) where Mr. Pass
was presenting his Aleph amps (mid 90's?).
I asked him about the lack of a standby switch to which he just shrugged
(What? Me worry?).
I guess the EU has got his attention on this matter.

I listen on average once per week for a few/several hours. So don't know, don't care, as long as the music sounds awesome, which is it does. That is all I care about.

Wait there will be government program cash for class A amplifier. You will have to trade your power guzzling power amp for a new efficient energy star class D amp. The gov't dealer will be required to smash the inside of your beloved class A amp for the cash credit towards the great sounding 2 dimensional sound stage newer energy efficient amp.

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.
