My whole rack gets powered down when not in use. Start it up just about every morning around 6am. Usually it just sounds a little "off" for about an hour. Sound stage is smaller, imaging is a little off. It's subtle, but there. Another thing I have noticed, on Sunday mornings it always sounds best, even when first turning on. Think this may be due to everyone else still being in bed, no other electronics on in the house, and surrounding area. The noise floor is definitely lower. |
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.
