What Would Be the Reasoning Behind Leaving Class D Amps On?
I think my Marantz Ruby integrated sounds better if it is just permanently left on. I'm a bit of a tubehead, but I've had 2 other Class D amps and I recall them sounding better left on.
I've seen a handful of manufacturers that even recommend their Class D amps be left on--e.g. PS Audio, etc.
In addition to the potential improvement in sound quality, I suppose keeping caps and things on might be easier on them too.
Do you agree? Do you know why this may be true or at least the theory behind it?
Thank you in advance! I'm super curious about this stuff.
Thank you @oldhvymec . I have a nice tube preamp here that I may drive the Marantz ruby with just to see how valves fronting Class D sounds. I did that once before with an NAD M22--I put a Schitt Freya in front of it and it sounded great that way, yet sterile on its own. The Ruby was voiced by Ken Ishiwata and he really dug tube amps, holographic pictures of sound and 3D imaging. So it's not as dry as that NAD that I had.

Next time I'm 6 drinks in and talking hifi with someone who cares or is not bored of me, I'm going to say this plebeian thing.... When Class A/B idles, it's only running at say 1000 rpm--to use a motor analogy. When Class D idles, it's only running at say 100 rpm. So, Class D needs longer idle times to keep stuff warm because its rpms are so low. PS. I have a masters degree in BS, but it sounds good. 🤣 |
mrskeptic what is that suppose to imply? That you're tough to please or everyone on AG has a lack of some type of higher education. A higher education doesn't always equate to wisdom about a subject. Nor do fact that others have obtained in their class rooms always stand the test of time. Science is malleable these days. Just depends where you look and what you chose to educate yourself with. Me I'll try anything at the neighbors house. I have 2 2" fire hoses I can hook to the hydrant in 2 minutes, FIRES OUT.
Science at work, hydraulics 101. And be nice, your a newbie. Sure you are.. :-) |
A stiff back would be a reason to leave them on.
Ok then,,, just try it both ways for a month. You’ll get people that swear upon stacks of holy books that it makes a difference. And others that don’t. (Personally - I doubt it matters) And they use such little energy that if you left them on all weekend I would not feel guilty about things like the climate… so you could power them off M-Th and leave them on Friday through Sunday… there are no hard-n-fast rules. |
