My gosh this has become very scholarly with respect to transients in a class D setting.
Isn't the harsh reality of class D is that it's to clinical and precise, and harsh. With class AB you get distortion and isn't that what harmonics is all about when you listen to music. It's all about the design and the colorations that are done by the amp designer. Most class D stuff is all about fitting lots of power in a small package.
And class D it's kind of cheap stuff so good luck making class d a preferable way to go
