Amps and Preamps has standby, but should I turn them completely off?


Hi guys, I know there has been discussions of this and the overall consensus seems to be leaving the Solid State amps / preamps on (or standby). I have a Parasound A51 that runs pretty hot. The heat sinks are hot to touch after running them for 2 hours. Ever since I move them to the 2nd floor (gets hot in the summer), I worry that they'd run too hot so I turn them completely off (by switching off the surge protector) after each use. Note that standby mode doesn't solve the heat issue -- it still generates a significant amount of excess heat. 

My question is:
1. Does turning them off after each use shorten their life?
2. Does turning them off increase the probability of failure?
3. Does the excessive heat damage them in the long run by leaving them on?

I am not too worried about warm up time because I use them 2-3 times a week tops. I just don't want the excess heat on the 2nd floor since it's already much warmer than the 1st floor. 

Thanks!!

I had a 1960 Fender Deluxe guitar amp that had caps that only lasted 45 years…damn…replaced them after noting some leakage (sounded fine with the leaky caps) and afterwards the amp sounded exactly the same. Lesson learned.
Brown tolex and knobs, and weirdly somewhat underpowered not quite matching the supposed output rating…I've seen this exact thing in other Deluxes of that model, consequently it made a great recording or harmonica amp (miked of course), but even with an efficient speaker (like a JBL or Altec) you couldn't use it with a drummer unless it was pointed right at your head.  A real grease fest with great tremolo.
