Leave it on or turn it off?


I have a Classe CA-301 amp. When I leave it on 24/7 it gets very very hot(SPACE HEATER). If I only turn it on when I'm listening to music it stays quite a bit cooler. What are the long term advantages to just leaving it on?(If any) Thanks in advance.

Some very interesting viewpoints. I never turn my equipment off. I would be willing to bet that 95 percent of equipment problems occur within 5 minutes of turn on. I know that is true for me.

One of the reasons why I am able to leave my equipment on all the time is that it is all solid state. I purchased a tube amp and preamp not too long ago and I sold them, on Audiogon of course, because I did not like not being able to listen to music on demand.

I do understand the environmental viewpoints that have been posted in regard to this topic. Most of the equipment that I own run in a standby mode when not in use.
As another CA resident, I must also take brown out into consideration when the voltage dropped below 90V. I used to leave my pre-amps and Marantz SA-1 on all the time until I blew the fuses 3 times in a row since the summer started. For those who owns the SA-1, a blown fuse means at least 2 weeks of down time since the fuse is hidden inside the power supply and is not a user-servicable part. To me, the sonic improvement simply isn't worth it (at least when we are still in the crisis situation).
Seems to me that leaving any equipment on leaves it subject to things like line surges and nearby lightning strikes. Am I wrong?
Unless you have surge protector. But still every time the hair dryer is turned on upstairsm the loud humming noise from turned on amp scares the hell out of me. I turned my stuff on about 1 hr before listening session.
