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

BTW, I have never experienced an SMPS giving up on me.... All have been rock solid.
But if/when they go, it’s with far more fireworks that linear ones, and they’re not as tolerant to being out of spec as linear ones either. When/if just the caps leak in linear ones they just smell and sound crap, but smp ones can go up big time if the caps go out of spec.
I repaired too many to trust them being left on and home alone, and it’s usually the whole smp board that has to be replaced as the boards/tracks get fried/burnt beyond being fixable.

George can you give us a couple of examples of the ones that go up in smoke?

I think that leaving any component on permanently can cause it to lose its best performance. Even Paul Mcgowen said if you unplug all your components from the wall and then plug them right back in, it can actually improve the system's performance.

Depends on the design of the component. Some sound far better and last longer staying on.

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.


Regards, G.
