I don’t have a lot of experience with Dynaudio but what little experience I do have I would not pair them with a Class D amp if it were my main system. Second system, sure, but there is detail in their designs which can be hard to separate. Using class D amp makes that worse. I’d almost say pair it with a “bright” amp but that may be dependent on your room.
Atma-Sphere makes a Class D monoblock design based on GaNFET output devices… 2 x 100 Watts… BTY, you should probably get a proper line stage preamp too…
