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?

Those who don't believe the science of global warming, or who feel its pace is too slow to worry about, may still want to conserve energy for several reasons:

1) $$$. You can save hundreds if not thousands per year in energy bills by conserving. Home energy costs will only increase in the near future as energy costs continue to rise.

2) Most of our power plants run on either oil, which in the U.S. is dependent on foreign sources (therefore to the political consequences of either acquiescing to those country's demands or sending our troops in harm's way to gain solutions in our interest; or our power plants run on coal which cannot sustain us and often has other negative affects, explained below.

3) It is hard science that power plants use up our limited resources of oil and coal, that harvesting oil and coal use up valuable lands (lands that when used for coal are rarely able to be used for other purposes again) and that power plants pollute the air and water around them.

Lets really be frank here. The left does have a track record and a bad habit of cozing up to radical dictators all over as long as their agenda is to hate America and its priciple values. I am sure many of them "dictators" don't turn their amps off because they could care less for the green house affect. Their to busy killing people the more conventional way than waiting for global warming to do its dirty work for them.
I'm not sure why there are so many people who believe that tubes require more warm up than solid state. It's exactly the other way around.

Tube circuits benefit from warm up, but less so than solid state in part because the tubes themselves have the best dielectric possible- a vacuum. That doesn't mean that the caps and resisitors don't get better after being on and formed, but solid state devices sound much more closed-in and "cold" at start up than a tube ever could. Frankly, even after unlimited warm up, solid state amplifiers never sound as open as a cold-out-of-the-box tube amplifier, but that's getting into another discussion.

Generally, I tend to leave most solid state gear on 24/7 and never do so with tube gear.
