Should preamp be left turned on?


Following a prior question, what's your view in the case of a solid state preamp (I have the Spectral DMC30SL...switch is in the back, I think).

I leave my Spectral DMC-30S powered up all the time. I don't really have to worry much about electrical storms here in San Diego.

How do you like your DMC-30SL?
From a recommendation right here in the forum, I just purchased a Pass Aleph P preamp from a fellow Agoner. It does not even have a power switch! It is an excellent piece.
I think they put the power switch on the back for a reason. I would take that as a manufacturers recommendation.
