Since the feedback is at DC, and up to a few Hz, and higher frequencies are filtered out of the (active) feedback loop, it is zero loop NFB as far as the music is concerned. A passive feedback loop can be made a bit easier, with feedback only at DC, and zero LNFB at signal frequencies.
Just like so many zero NFB tube amps out there have cathode resistors that are bipassed with a cap, they all have NFB at DC and very low frequencies.
