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?

Listen and decide. My Class D amps are the best I’ve ever had by far. They sound great always with most any speaker and that’s all that matters. Gotta match to right speakers for absolute best results though just like any amp.

Plus they are most efficient. That’s a good thing for amps just as it for speakers. That is really the thing that distinguishes them most especially for use with most any power and current hungry modern speaker that also tend to be smaller and more extended meaning power and current needed for best results. It’s a natural technical match that results in top notch performance in most cases out of a smaller more easily handled package which also means better sound possible for more people.  Of course personal preferences regarding what sounds best really is totally subjective and preferences will vary.
you have to use a low pass filter and some think the attendant problems with that cause SQ issues

you also have a lot more EMF generated

and more...

Class A maps work relly well in the arctic where you can use them to heat your igloo

I have no dog in this fight since I use a Sunfire
The day will come when Class D will compete and very well be better than any linear amps tube,s/s, class A, AB or whatever, BUT!!

 Class D needs much higher switching frequency (needs to be at least 5 x higher) technology isn't there yet but in the future it will come, only then will ClassD become a contender. Till then good for budget hifi and subwoofer/bass amps.

Technics has progress the Class D race and developed 2 x the present switching frequency with their own made components, in this amp but it’s very expensive $20-30k

When the switching frequency is 3mhz or better, then it can be called hi-end, and will own it myself, then my linear heavy boat anchors will be sold or become door stops.

I have only listened to a couple of brands of Class D amps and was totally unimpressed. That pretty much steered me away from them but I'm sure there are some good ones out there. I'll stick with my Class A thank you.
As Mapman said you have to listen to them and decide. Some people are very pleased with certain class D amplifiers. Thus far in my experience a high quality class AB and definitely class A are better sounding. I’m with George on this one. This could change in the future with further class D development, so time will tell. For some listeners such as Mapman the future has arrived and I can appreciate that per their perspective,  truly an individual call.
