How does it work? Why the example use only +/-14V, and the selfoscilating frequency only 100khz?
Won't work for +/-50V at 400khz?

I think that MG didnt read carefully...The class d just lift the low voltage psu of the class a amplifier to provide high voltage output swing. Since it lift the power supply form the middle point, no power supply perturbation will affect the class A stage. Funny that this is very close to the labgruppen patent...
I can only guess, this schottky+1000uF is a clever way to make use of the residual of IRAUDAMP system. IRAUDAMP use pre-filter feedback point.
Fredos, I think it is a bit different than labgruppen patent, since the sources of final mosfets are only connected to schottky+cap bank floating supply. I also don't know how can we adjust the margin (VDS) of this scheme. Maybe adjusting the cap value?
