Maybe the term "coupling" is in any case not the best one to describe the role of a PS capacitor, since "coupling capacitor" carries the connotation of a capacitor between one stage of amplification and the next. The PS capacitor is in the audio path, and to that extent it has features in common with a coupling capacitor.
That's always been my opinion.
With regards to Banat's circuit (seems I saw that proposed on DIYAudio a few years back) it might be a good idea to use resistors that are more like 100 ohms. That would make the caps smaller and the bias would not be self bias as it would still need some bias voltage, but not nearly so much. :) Each approach has its own set of problems...
