Can you leave class D amps on and not ever turn them off?

I have had the following class D amps in my system over the years: Bel Canto REF500 and REF1000 Mk.2. Rowland M312 and M925. In all cases, I have left them on 24/7 while monitoring the local wheather like a hawk. Whenever thunderstorms are in the forecast for the day, I always turn off the entire system and unplug each component from the AC outlets.


BTW, with all amps that I used in my system, class D and A/B alike, I have experience that the audible behavior is maximized if left on for about 24 hours while generating some kind of low volume sound... I usually connect an old FM tuner set to interstation hash.


Class A/B amps have included Aragon 4004, Rowland M7, Rowland M625, Rowland M725. All benefited from being at full power 24/7... Invariably took 24 hours for any amp to run at its sweetest. It was possible to run M625 and 725 24/7.... Tried that on the old M7: costed me $150 of AC over a two weeks stretch *Grins!*

 


BTW, I have never experienced an SMPS giving up on me.... All have been rock solid.

     

Hi Ph.D.... YOu are absolutely correct.... I have observed the same thing, and should have mentioned it.


Fact is that with all my amps, class D and class A/b alike, I turn them off once a week for a couple hours for the very reason..... After a week or more days of running continuously, the sound just sags a little bit.... Turning them off for one or two hours and powering them up again freshens them up nicely.
