I have a PS Audio Trio A100; the manufacturer recommends leaving it on all the time. I power it down, though, when using headphones. Does anyone have experience powering a class D amp on and off on a daily basis?
My ARC 150.2 stays on 24/7, unless I'm away on vacation. ARC recommends leaving the amp on, and various reviewers have commented that sound quality improves up to the point where the amp has been on continuously for several days.
I'm guessing you power it down as otherwise the speakers would be playing while you are listening to headphones? If that is the case it is probably not detrimental to the amp to be turned on/off occasionally. Though with the power switch on the back, it may be a pain to reach around.
The reason is that class D amps take much longer to run-in with their IECs and turning them off is akin to turning back the clock on the run-in period where the amp will need on/'run time to sound its best again.
The only time I turn mine off is during bad storms and if I am going to be away for more than a week during thunderstorm season. I do use a Hydra on mine in any event.
