Leave amps on or off?


Is it better to leave amps on or off when not in use,not including tubes.they do sound better warm but will affect the life span?

I have recently started leaving my SS ARC 100.2 amp on all the time, and I can tell you that the sound is MUCH BETTER! I have a tube preamp which I leave in standby mode when no being used. Of course once the preamp warms up the sound is even better, but by leaving the amp on all the time I am amazed at the improvement.
I have always left my solid-state amps (Adcom, Bryston, and others) turned on at all times (except during electrical storms, or when away on vacation). Over a 13 year period, I have only one problem that required repair (a power transistor burned out). I think solid-state amps sound better when fully warm, and the warm up/cool down cycle is harder on the amp than being left on all the time.
What is the life span of the green diode indicator for standby/left on position. Has anyone had to replace them due to their units being on all the time? Thanks
I always leave my sold state gear fully powered up. It takes at least a full day or so to peak from a cold startup. Thermal cycling reduces equipment life, which is another consideration beside the higher electric bill. The energy isn't really wasted (about 9 months of the year it contributes to household heating) & power is cheaper in the midwest nowadays than natural gas anyway.
To "7671" your LED's can actually last longer than you will.
I think that this topic has been covered in depth many times over. Anybody that has done comparisons will tell you that SS amps sound best after being on for at least 24+ hours. They also last longer being left on all the time (all things being equal ). While LED's can last a long time, i wouldn't count on them running anywhere near "forever". I would worry more about capacitors than i would LED's though, especially if you are turning your amp on and off. Sean
