Musical Fidelity leans towards a warmer sound than say Cambridge Audio or most Class Ds. Class D is not for warmth. Hypex is probably the popular modern implementation that comes closer than Purifi and definitely Pascal. I’ve heard Atmasphere Class D and the sound was more like his tube amps than not.
So don’t make the mistake of thinking all Class D is the same. Some vendors offer different op amps up front that adjusts the sound to different preferences. VTV for example.
Personally, with B&W, which I have owned, I’d probably lean towards Pascal or Purifi. Hypex ncore done well would be perfectly fine. I tend to lean towards detail rather than warmth.
