Solid state power amps.; on or off?

My Classe' Ten has been on for 9 years without a problem. The only time it's shut down is component/wire change, contact cleaning and thunderstorms. No problems.

I never tried leaving an amp on all of the time until I read this thread and have started to leave it on now, I am a believer! After just a few days I have noticed a HUGE diference in sound in the most crutial moments, the first few minutes of listening actually sound good, go figure!

....any component that lasts 13 years with either no servicing or just one servicing is a gem. Craig.

Yea Craig, if you ever have a chance to pick up a Proton, they are ausume. Best piture tube made (Hattachi). I got mine at a close out dealer for 70% off and it was still over $1000, but that was the first and only issue I've had. Now it just needs to last another 13 so that HDTV finds it's place. J.D.

I have started turning off the Musical Fidelity SS amp attached to our mini system due to the power problems in California and it does not sound as good at it did before (when left on 7/24), not nearly as much detail at low listening levels which is how I use it in a near field setup. I still leave the CD player on as it does not draw much current.
