What Class D amps will drive a 2 ohm load

I wouldn’t believe any manufactures, specs only independent ones.

Check out post #42. $5500 all out Apollon stereo amp using NC1200 modules A/Bed with $20K mono Krells. Sexy amp!

I have no idea how they sound but according to Anthem their M1 Class D Monoblocks if connected by 240 volt will drive into an open circuit or short circuit. 

• Flat frequency response into any load, without having to resort to digital conversion or equalization to compensate.
• Stable into all loads including open circuit and short circuit.

According to this the M1s are manufactured by Paradigm -   http://www.theabsolutesound.com/articles/anthem-statement-m1/?page=4

This is the OP again...it sounds like I am hearing Class D might not be the best for tough, low impedance load speakers.

If that is indeed the case, why is this and what has to change in Class D design to achieve it?

The Mosfet output transistors themselves as well as the output filter, which both have not changed much since it’s inception.
The GaN output transistors are maybe going to change that with optional far higher optional switching speed available, so then output filter can also be far higher up, then there’s also no phase shift down into the audio band. But this also needs small heat sinks to be used, as you can see below.
But only one amp so far has utilized that combo this the unobtainable Technics $30K SE-R1 power amp.
