High end Class D amps?

The best measuring class D amp modules at this time are the purifi and Ncore. That's not to say others like ICE or Pascal are not good, most likely they would be indistinguishable in properly designed implementation. As an example  the Dutch and Dutch  8c uses Pascal after testing various modules because they could get them for a better price and couldn't hear or measure any difference. I believe Buchardt uses Pascal as well. There is no reason class D amps should be expensive at least by audiophile standards unless the company uses high priced case design, name recognition,  added coloration through implementing purposeful distorion by way of tubes etc... , more features like the Nad M33, room correction,  dac, streamer. 

Then next you lot may as well just tell us to use this 6000watt!!!!! Class-D Behringer for just $600us.

Let me tell you, that on the Wilson Alexia in an a/b it was trounced by the 40 x times less powerful!!! Gryphon in dynamics and bass control. The Behringer was thin, anemic, weak in the bass and sounded like it was struggling

This post is using a Guilt by Association logical fallacy, which is that since the Behringer amp is class D and struggles, therefore all class D amps will struggle on the same load. Logical fallacies are false by definition.

 It's my understanding that efficiency has been the primary advantage and raison d'etre of class D amps since the get go. Their further efficiencies in weight, size and cost are just peripheral advantages. 

One advantage of class D amps that isn't mentioned so much is how they make distortion, and what sort of distortion they make. The distortion is mostly based on the linearity of the encoding system and deadtime used in the output section. A good deal of this distortion tends to be lower ordered harmonics. A second advantage is that if you use a self-oscillating circuit (which is an idea that's been around for about 20 years or so) then it is possible to put far more feedback in the design than is possible (for the most part) with traditional solid state designs. This is how the Purify module is capable of such low distortion. This also results in an output impedance that is so low its pretty difficult to measure. **That** simple fact means that the amp can act as a voltage source into speaker loads that are quite a bit less than one ohm, even if its power supply can't support doubling output power at full power into such a load. But if the amp is playing at a few watts (IOW: normal listening volumes) it will do so with ease.

Anybody tried the Orchard Starkrimson?

No never heard the Orchard but the owner posts on ASR if you would like to ask some questions. He had a 10% off sale before Christmas.
