Yes Class D does lots of things right except for output graininess, since long ago I have said ferrite output coils cause class D to sound 'off'.I just read an interesting paper by Bruno Putzeys titled Hysteresis Distortion:
I have a personal aversion to class D.
To do it well you need a lot more skill than you would to design a good class A or AB amp. But the thought of passing some chamber music through a thing banging up and down 100 V at 300 kHz seems unseemly to me. Or maybe I’m just biased after selling class D chips to Sony for boom boxes.
Fine for bass.

Sweet prejudiceWhat about 5G?
5G is terrible, they are spreading the coronavirus.
So let's put them to fire
Unfortunately, there are always people willing to believe this kind of complot theory nonsense, like those who still embrace the flat earth theory.
This has already resulted in twenty five 5G cell sites being set to fire in the Netherlands.
Maybe 5G has health issues because of radiation, but if so, then 4G has the same problem.

Isn‘t 5g on—more or less—the same wavelength as WLAN? Oh dear oh dear we‘re doomed.
Same here - quite a few burnt down or damaged.
Amazing how people link things together and draw conclusions about stuff they have absolutely no clue about.
I tried to explain ionizing vs non-ionizing radiation to a neighbor (unrelated discussion) but they could not get it. If you lack an intuitive grasp of things scientific, you will think all this stuff is magic.
It’s almost as bad as suggesting a bleach injection to cope with a viral infection![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

Yeah the whole 5G silliness seems more of a European thing? Although I saw protests in NZ as well. It's interesting seeing how regional some of these things are. (not being judgmental as goodness knows we have our own tropes, see captain l'orange's health "recommendations")
or sell it for parts or repair

Those were working amplifiers with AP plots showing performance in the listing.
However the tale was about folks named D. J. Xxxxxxx!

Yeah - might be more of a European + UK thing. I think there was some celebrity pushing the theory as well.
Nuts.

David Icke is hardly a celebrity. Weapons grade nut job describes him!

Of course captain obvious
Whilst Bruno has 'fixed' something he found in measurements with the purifi modules he has never said that he could hear the problem, but choses his words carefully in accepting that others could or not.

Bill,
I fail to understand why you would want to insult nut jobs!
David Icke does require an entirely new catagory. Perhaps Scott possibly being an archon can help us!

There was someone else more mainstream - female.
Of course captain obvious. I have to say that I have not heard one of the better class D amps (icepower/hypex/purifi) but I am wary of people who say it's 'grainy' because everyone who claims not to like class D says the same thing therefore I feel they read it in a review and decide not to like it based on that.

I heard a Hypex based amp at the NWA last year. It sounded very good.
But, the system was really geared towards what I call ‘hyper reality’ sound - studio mixed stuff with ultra bass and tizzy top end. Impressive but fatiguing after a short while. I prefer something that sounds more relaxed and natural.
