I took a look at the website where they push this idea.
There's a lot of misinformation. I'm guessing its written by the marketing department, by someone not having a grasp of the actual engineering.
The most obvious example is stating that a class D amp is digital and conflating the two. Class D amps are analog and employ switching. They are not digital; if there is a digital amplifier its not class D. Just so we're clear on that.
Its an interesting idea but one question coming to mind right away is since the class D is providing the current, it therefore has to be providing the voltage as well, so the class A portion would be doing nothing! So I have to assume that the explanation is simply incorrect.

- 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)
