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?

So it's come down to mud slinging. 
Not from you sunshine, I think everyone knew I meant megahertz as there's 1,500,000,000 difference between the two.

I believe you won’t find one tech guru here on Audiogon that would recommend a Class-D amp over "big current" linear amps for these kinds of loads, sure they may work, but are you getting the best from them? I think not. 2nd graph

BTW: Carver 120 and Kronzilla Mark II are NOT big current amps, sure they consume big current, but they won’t push it into speakers load like these Appogee’s

It is far from mud slinging, buy it appears that you make strong technical statements on the subjects that you are completely unfamiliar with.  I pointed out units just to show that you don't have any electrical engineering education.  This thread is not too bad, but your crusade against Delta-Sigma converters is plain insane.  Cheers.

I understand your just protecting your JR120 investment, that "if" you had the knowledge you could have built for 1/8th of the price. http://www.usaudiomart.com/details/649188442-icepower-200asc-modules/

And I’ll bet you’ll be the first to sell it when the technology comes that get’s rid of the switching noises problems without effecting the amps sound.

It’s about sound George. Obviously from your many condescending posts, you consider yourself the foremost "guru". Try a little humility and you might learn something.

Best to you George,
Dave
