Do I NEVER shut it off…?

  Yep! 

IME SS amps sound best when left on continuously. I listen to my system at least a few hours daily (usually more) so leave the amp on unless I'm out of town for a few days or we're having thunderstorms in the area.   

I would not leave a big power amp on continuously. 1) They are powerful enough that if something goes wrong it could burn down your house. Unless you put in a tiny fuse, which would defeat the purpose of having a big amp. 2) In today's world there is no excuse for burning up the planet just for a bit of euphoria. If your amp needs to be on all the time it's time to change it, good excuse to go shopping!

@ asiaaudiosoc7 - 

1) Could you please cite examples of amps burning down residential houses.  Provide links for articles specifically noting the cause of the residential fire that destroyed a home was a high end audio amplifier.  

2) There's no need for excuses for leaving the amp on if it improves sound quality.  That's the entire point of having better equipment.    

My Herron M1 amps have been on for years.  I only turn them off if I'm going on holiday for more than a week or if we're having electrical work performed on our home.
