My tubed pre- amp and amps are turned off. I notice that the sound isn't right for about 40 to 60 minutes with improvements over the first three hours.
My CD player has a class A solid state output stage, and the owners manual clearly states that it is never turned off, the off switch merely powers down the display. It is slightly warm to the touch.
My old Classe 301 sounded best after being on all weekend, and I generally left it on.
So much for sound, now about the longevity issue. As an electrical engineer, I was told that a good rule of thumb is that you half the life expectancy of a component with each 10 degrees C rise in temperature. I do not know if this holds true over the entire operating envelope, I would tend to think that the first 10 degrees would not be as bad as the last!
That said, if the equipment is properly designed, the components should stabilize well within their specified operating parameters. So, perhaps they may last 50,000 hours instead of 100,000 hours. No big deal, I don't know very many audiophiles who keep stuff for that long anyway!!
I say leave the SS stuff on and enjoy. Fix it if it breaks. Don't stress.
