Leave an amp "on" permanetly


I understand that tube amps need to warm up sufficently before they can reach their potential. Is this also true with SS amps? I own a McCormack DNA-1 deluxe, and I hear a discernable difference when listening to my system "cold" versus "warmed-up". Do you also find this to be true?

If so, would people recommend leaving a SS amp on permanently? Could I damage my amp by doing this?

I left my Pass X-250 on 24/7 for almost 2 years. Nelson Pass told me it required about an hour to really warm up and come into it's own. When I asked about just leaving it on, he said it wouldn't hurt if I could take the power bill and the heat. I'd recommend you email Steve McCormick and ask him- after all it's his baby.
I think it is better to turn components off when not using them for more than a few hours. I have not heard of a single example where the life of a component was shortened by routine switching on and off. This is simply another bit of audiophile folklore that is bad for our environment.
I didn't know we were tackling this from the green angle.

Well, if our aim is to enjoy music without negative environmental impact, we can :

1.just go to live concerts. Oh wait, you have to drive there and that's adding greenhouse gases. Or..

2.you could go all solar- oh wait, making those photovoltaic cells is kinda nasty, not good for the environment either.

3.Wait- windpower! Uh Oh, kills birds like crazy- giant airborne cuisinarts.

4.Okay- hydroelectric- uh oh, damming rivers is bad for the environment.

5. Just play acoustic instruments! Nope, gotta cut trees.

6. Just Sing! Nope- the EPA now says that what you exhale is a pollutant, so can't do that either.

Damn it, people are just ruining this planet!

Hmmm

I'd just turn myamp on when I got home from work, cut it off before bed. Maybe then you can have it sound good AND live with yourself despite mankind's inherent dirtiness.
A Dealer Man I know says that, in his experience, tubes take an hour to stabilize and sound good and solid state takes 24 hours.

So a good "green" compromise is to turn your amp on Friday morning and turn it off Sunday night for a good weekend listening session.
