Atma-Sphere Class D… Amazing

If that is so either the opamps were really terrible or the designer didn't know what he was doing! With any module you really don't need a lot of gain, so why would decent opamps affect the sound?? Answer: if the buffer is properly designed and if decent opamps are used, they won't.

Plenty of people have bought in to the "everything matters, everything has a sound" mantra. As I am sure you are well aware, audio people can be quite insecure and easily influenced by the siren song of other's wacky claims. Just look at all the audio voodoo on the market- if snake oil could only be refined into gasoline we would have $0.25/gal gas again.

 

Value picking seems to be easier when applied to established technology. Class D amp tech seems to in an evolutionary trajectory.

Current state of the art class d has performance with distortion at the limits of human hearing. Purifi, a leading class d amp company, is focusing their attention on drivers these days because in their opinion improving their class d amp has reached the point of diminishing returns. Speaker drivers are the weak link in the chain, thus I wouldn't worry about buying a state of the art class d amp only to have it materially improved in 2 years. Besides, one can get the state of the art for around $1000 these days.

@jjss49 

sell products to retail customers... you just get used to alot of random noise from purported know-it-alls

Clearly one need not be selling products at all to be subjected to a lot of random noise from purported know it alls.

@kuribo Ok, I know I’m feeding the troll here, but please share where one can get SOTA sound for $1000.  I can’t wait to be educated.  Moron. 

He has to be referring to the Hypex, as the purifi are more like 2k$.
But the Hypex are really pretty good.

To me they define the bottom separation level, of the Class-D “high end”.
