Class D Technology

So I get the obvious strengths of Class D. Efficiency, power output & running cool which allows for small form factors. I also understand the weaknesses somewhat. 1. Non-linear & lots of distortion that needs to be cleaned up with an output filter. 
So my question is, if it weren't for efficiency & power, would there be any reason to own a Class D amp? Do they beat Class A in any other categories that count for sound quality?  
I'm not sure what NuForce are doing.  It is possible that they adjust supply voltage to signal level, but that would only mean much lower noise (than for instance Icepower)  at low signal levels.  Noise level at max loudness would be the same as for the amp that doesn't do that (assuming same switching frequency and the filter) - equivalent to about 4mW on 8 ohm speaker.  Icepower doesn't adjust the rails and I'm pretty sure Hypex uses constant supply voltage.   With constant supply voltage amount of switching noise at 90% or 10% duty cycle would be most likely 1/2 or even 1/3 of the one at 50% duty.
Not much doubt that class D noise is independent of signal levels, and poses no unusual threat to speakers.

I own the Spectron monoblocks. Superb sounding amps, amazing value relative to cost.
My advice for anyone on the fence is do your homework, listen and decide for yourself. Only then will you know.
Well Mapman, if you would’ve said this at the beginning of the thread, we could’ve saved a lot of typing.

It’s what I did, and decided class C wasn’t for me.
AFAIK, class C is a poor choice for audio (better for FM transmitter).

Hate it when I make stupid mistakes like that.
