Class D amplifiers have very little phase shift

Hmm all my Class D amps sound fabulous. Best ever ( I have 8 Class D amps that I know of in my house).
I guess this is one reason for that.

Can you guess I am a Class D fan?  

In a self oscillating class D amp, the feedback itself is used to correct phase shift. Its pretty effective in this regard.

But I've been listening to a class D amp with zero feedback, switching at a fairly low frequency (400KHz), with a rather conventional filter, and it does not sound like phase shift is a problem :)


The article at the link is correct. Understanding filter theory is really helpful in conversations like this. If only one party understands the theory though, its very difficult to make any progress.

the dynamic load of the drivers and crossover will cause massive changes in the impedance of the speaker system. The drivers shift all over the map, thousands of times per second.

Not really relevant and also, what does this even mean?

True enough, Ralph, I get it, but that is horse chasing after barn doors are open, and there is always a better way.

Sorry, I can't make out what you're trying to say here.
