I used to leave my pretty good system on all the time because it always sounded better after an 1 hour or so of warm up.
After some years had passed the system seemed less pleasing I did all kinds of tests and just shut it off one day in frustration.
I now know that my particular amp sounds best when a little warmed up but begins to sound coarse after 4 hours or so (yes it runs very hot, always has).
I have contacted the manufaturer who says he has never experienced this and would be happy to look at the amp. Its about 90 lbs and needs to ship to the opposite coast so I'll wait until things get worse.
For now, I turn it on when I wnt to listen and shut it off afterwards.
