Ok this makes more sense. THere are caps on the output as part of the HF rolloff. Not quite the same as a cap in series to block DC since the caps should be shunt to ground and the inductor(s) is in the signal path.

I don't know if some other Class D amps are using "traditional" global negative feedback or not but the latest stereophile review of a tri-path amp shows a rise in distortion with increasing frequency, which is characteristic of global feedback. I would be interested to see some raptor measurements to see if it is possible to tell what the dead time control is doing.
