Maybe it self oscillates at 200KHz and the audio input modulates it. Maybe
nano technology is not shown in schematic.
** The technology is right there in front of your eyes - just look how the
main NFB loop take off comes AFTER an L-C filter at the output. Recipe for
HF oscillations - no ?
Here is the web site of the guy ( Bruno Putzeys) who invented that
arrangement - while employed by Philips.

Apparently, he has to pay them royalties use it himself.
