Class D Technology

If bought down low to erase most of the switching noise, this intrudes into the upper frequencies of the audio band. Which makes it very smooth but robs most of the harmonic structure of the mids and highs, this "could" be compared to tube or class A s/s smoothness.

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

George you conveniently forgot to mention some think the sound including the high frequencies are quite good and not flawed.  

Lets not selectively filter feedback just to help make a case.   

Im listening to my Bel Canto C5i Class D integrated with Triangle Titus speakers currently.  Other than the clean articulate bass I could easily think the amp was a very resolving and clean and dead quiet tube amp.  The treble is as good or better than most anything I have heard.  The sound draws you right in. 

So so let's stop trying to convince people the technology is flawed or does not sound good.   It's as good as anything these days done well.   Done well is the key like with any technology old or new.  

Technical difference aside(which I am not an expert), purely based on the sound, tubes has significantly more naturalness and fatigue-less, yes I understand that every  own has  own preference, but end of the day we are thriving for the sound what we like, which give us endless pleasure and to me Class-D still lacks the connection to the mind which interprets as its as more of digital sound...
Yes, Class-D had the advantage of running cool, clean sound, lower utility bill....it matters with every own of us what we prefer the beautiful analogue  sound or the convenience of the Class-D technology??

There is absolutely no fatigue with the C5i driving any of my speakers including some that are documented to potentially lean that way with the wrong amp. 

Mapman +1.

Georgelofi - if you don’t like the sound of particular amp or even class of them just say it, but making up pseudo-scientific reasons is just plain silly.
