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?

Murgesh what clas d setups have you heard? Why assume that what you heard is indicative of all cases? That’s called jumping to conclusions. My experience is the exact opposite of yours.


The c5i is in fact a digital Class D integrated amp ( not just class d). and the sound is nothing like you describe.

I recall when I was in college I could hear well to 20khz. I know because I ran tests.

I also found it much harder to get sound that was not fatiguing. This is back in analog days even. 

These days I know I cannot hear to that extent which is normal for ears my age. I find listening not fatiguing at all and can listen enthralled for hours and not want to stop. With most any kind of music or recording. Well except the occasional really bad modern loud pop mp3. That’s what its all about. Maybe there is some advantage to getting older after all.
Mapman, with all due respect, how old are you?

Mapman, I am using Spec RSA717ex, it has class of its own ,Spec is better sounding than the  Class AB Luxman-505ux I have used previously, praised in various reviews, luxman sounded cold  and suppressed to me.
And all my inputs given in my previous posts are after comparing Spec with Audio Note Oto phono SE, only 10watts....

My class D amp has 60kHz -3dB bandwidth. Georgelofi - you must be a bat?

What brand model? Maybe I can find some non affiliated bench tests

Even so with those figures do some homework at -3db at 60khz you will have phase shifts all the way down to 5khz,  because of the low order of the switching noise output filter.

Cheers George
