High end Class D amps?

this is a good discussion

i too am interested (in a more technical, geeky way) to understand WHY a class D amp delivers higher damping factor (let’s use that as a proxy for bass control and quality) than a similar class AB amp using standard transistors be they mosfets bipolars etc etc... let’s say the power supply quality is the same and the input stages are well designed... the switching amp or transistor effectively ’gates’ the power supply from the speaker load at the various frequencies asked of it, per the input signal

why is it that the class d module does it better than a well designed set of transistors, with a higher degree of control/accuracy?

The best amplifier I’ve heard is in class AB, bettering other much more expensive class A, AB and D amplifiers. I have had class D amplifiers which better class A and AB amplifiers. I have also had various D amps which vary widely in sound quality. So what I’m saying is that there is no such thing as a better class. It really is not as simple as which class.

These are the most interesting Class D amps I've yet come across, using  Korg Nutube buffer, which emulates a triode.

Unfortunately, they don't seem to have made it to the US yet, but if Nord, Apollon and March have, surely they will too.

No mention of PS Audio... not high-end enough I presume?
