Amp — Leave on or turn off

Have you listened in the morning before when the amp was off all night and had a different result?   Personally, after being in a dead quiet room for 8 hours, my ears are much more sensitive in the morning then the night before.  Even when I listen at night, or during the day, I try to have some quiet time before I listen.  Relaxes me so I can better enjoy the music, but also gives my ears a rest.  

I left my McCormack amp on 24/7 (unless we were leaving for a week or more) and only had to replace a fuse over 20 years.  McCormack recommends leaving the amp on I think partly because many electronic parts don’t like constantly cycling between cold and warm, but I know some other manufacturers recommend turning it off so may be product specific (obviously you don’t wanna leave a Class A or tube amp on).  Anyway, I’m with you on just leaving it on.

And there is often less electrical activity in the neighborhood mornings.

I often forget to turn an amp off overnight for no net gain in SQ.
