Its nice to have a 'solid state' amp that sounds as smooth, liquid and detailed as a good tube amp and that both are simply sounding true to the recording. If compared side by side on a speaker that both amps are happy with its really obvious from the neutrality of the class D that with our OTLs we were on the right course all along they sound so similar they are hard to tell apart (what you hear as different is the bass presentation, since the class D acts as a near perfect voltage source, and its also a bit more focused). The class D project for us was really affirming of this idea it measures considerably lower in overall distortion compared to our OTLs but otherwise has a very similar distortion signature. Reducing it, as long as the resulting distortion signature is benign, is paramount to getting things to sound real. One has to be pragmatic that distortion can't be eliminated.
In high end audio, the assignment is to get as close to the musical event as the recordings will allow. Encouraging distortion, even if its lower orders, IME while euphonic, results in less resolution- it might be fun but it does not bring you closer to the musical event. While the lower orders are useful for masking the higher orders, if you can reduce the overall distortion signature, the result is greater focus, greater resolution, but otherwise the same organic (musical) presentation.
I'm not aware that sag in the magnetic field results in lower ordered harmonics! I would expect greater IMD and slower risetimes.
