In search of info from the technical guys

I am a member of the Golden Ear forum on their site and directly asked the Moderator if the Triton Reference speakers which I own are using a N Core amp or Ice amp for the subwoofers. I was told neither, their amp is their own design. When I pressed for more information, he wouldn’t really answer saying he is not privy to that information.

For the Techs, is this possible? What other form of Class D amp would there be?
