Purifi Class D: Junk?

I will not post after your next "always have to have the last word" post. 

Hello, does anyone know the current engineering revision level of the Purifi class (J)unk Amplifiers? Putz apparently says Class A could do with some improvements, but Class (J)unk cannot stand on its own merits. Someone said that there were amplifiers that were over $20000 with these modules inside them? Talk about a ripoff. The % profit margin must be in the 4 digits.

Any Purifi module isn't junk! - they are all excellent. 

The problem was the mix and match approach that spawned this old thread had the expected result. If you want a class D amp to sound good, you have to give it a respectable power supply like you would with any other amplifier. If that happens to be a switch mode supply, to really make it work it should be designed for the application rather than something off the shelf, even if that off the shelf source is excellent.

The input buffer can have a big effect too. Its a sad state of affairs that so many class D amps get shot down on this account.

Any bugs in either of these departments and the whole thing goes down the loo.

If these issues are properly controlled you find that a class D amp can be just as good as the best class A amps price no object.

@kawzx7,

I have no horse in the race. But looks like Class D bashing is your favorite past time. Your post reminded me of another person (george), who used to frequent here a few years ago, from down under, who did the same. If posting the above made you happy, then good for you.
