I have a Rouge integrated amp with stand-by soft start. Truthfully, after a half hour warm up it sounds great and additional hours of warm up seems to make no difference, so, except for periods when I plan to listen to music for a couple of days in a row (even then usually turn on in the am and off at night unless on an all night music binge) I see no point in leaving it on 24/7. I also have a Audible Illusions Modulas II preamp, also with a stand-by soft start and left it on continually only during periods of extended listening and off during periods of not listening. I had to change out the tubes only twice in 25 years. If your pre amp has a soft start and you listen to every day, I agree with paul79, on once off once each day.
Is it a OK to leave tube pre-amps powede up 24/7
I’m relatively new to tubes in my hifi setup. Recently went from SS pre to tube ARC pre-amp and a Croft phono stage.
I have always kept all of my SS gear powered up 24/7(and still do), but I shut down my pre-amp and phono stage now after I am done listening for the day. I power them up at least a half of an hour before I put anything into play.
I would prefer to leave my tube gear on all the time, but am concerned about premature tube wear.
What would the tube folk here think about 24/7?
