I own Atma-Sphere Class Ds and they stay on 24/7 unless we're going on vacation. When I first got them I experimented with various warm up times and they always sounded better the longer they warmed up. Since I often don't have a lot of time to listen keeping them on gives me more enjoyable hours. They stay cool to the touch and draw little power so I see no downside of leaving them on.

@armstrod and @atmasphere Thanks for the feedback. The staying cool part I think is a big deal!! I've not done a direct measurement of Hypex to ICEpower but I think ICEpower are cooler when idling, in general. I may be wrong. I wonder if that in some way delays their warm up time? |
@erik_squires Any class D amp will be cooler if idling. Our amp has to be pushed pretty hard and for a while before it seems like its any warmer. At home I play it all day and it stays cold to the touch. What little feedback we have regarding the on all the time thing suggests that it doesn't matter if the amp is playing a signal or idling. It only draws about 5 Watts at idle.

@atmasphere - Of course. I should have been clear. It's my impression that ICEpower amps, at idle, draw less power than Hypex amps, at idle, with similar rated amplifier power. |
I don’t notice much, if any difference when my class d amps are cold versus when they have been playing for a while versus when they have been on standby. Maybe if I listen hyper critically, but doesn’t seem worth the trouble. Now my class a single ended first watt amp definitely needs to warm up. No comparison between that and the class the amps |
