Should Class A Amps be left on??


Ok- Audiogon members need some advice here. Should Solid State Class A Amps be powered all the time? Have heard two school of thoughts on this. Apparently from what I have heard this is a moot question for Class A/B amps due to the usual low biasing of A/B Amps. From what I have been to learn so far Class A Amps should be left continously on.

Nelson Pass expects 20 years or so from the Alephs because they "run hard". As energy consumption is also importantly an issue, I too try to flip my 30 amp switch on my ACME cry0-outleted junction box with my toe about an hour or two before listening...or listen to FM background before CD.
I'm hoping that this 10-15% on-time leverages my Aleph MTBF to at least 25 years (I'll be 75). We'll see....
Sometimes I think it takes mybe 2-3 hours for the Aleph 2 monos (300w idle each) to get liquid and VERY resolving.
But it could be my (our) hearing apparatus acclimating to the listening environment, like occurs at a live concert.
Yeah, I guess I could afford to leave them on 24/7, especially in the winter, but I'd still feel like they'd age due to thermal load. I have them each sitting in holey
plastic 1 ft-cube milk cartons, hanging a foot under the basement floor joists, so they get convection cooling from UNDERNEITH, too. Hope it helps....
