I leave my 300 turned on 24/7 (with surge protection). It does take a couple hours to reach it’s optimal performance after a cold start. Bob Carver has written that it can be left turned on and that constant voltage to the unit will not hurt. (not a good idea if your AC is unstable, IMO).
Plus, I don’t like the idea of an in-rush of current every day when it’s being powered up.
I too have had my amp refurbished by Bill Flannery. I have a 300 first generation, and he upgraded it to meet the specs of the Sunfire 300-two (3rd generation). It now has a much lower noise-floor.

In my situation the sunfire sound is effortless . From low , med to high volume it does not change it’s presentation . No nasties in any frequencies . Smooth sounding .@maplegrovemusic, that says it all. I can only add that the Sunfire "house sound" is lush, warm, with wide and deep soundstaging. It’s very "non-solid state" sounding.
