I think it's more involved than that. I get the fact that Class D is analog, but when the engineers demonstrated the amp, they disconnected the Class D section, and just use the Class A portion. That only outputs a few watts. The claim is that the Class D provides the current, while the Class A supplies the voltage. It does seem like the Class A does switch the current source.No other amp I'm aware of uses this approach. I can report that it sounds outstanding, and seems to have lots of power.
I'm not sure how it actually works, but it sure sounds better than most any setup I've come across. I agree the write up is likely written by marketing, but I think the approach is unique, to be sure.

- Not contesting that the amp works, but go look at their website; you'll see it is indeed a trademark - Ralph 10:02:48 03/31/22 (2)
