I've read almost all his articles and owners manuals and seen all his BA lectures. Can't recall anything of the sort. He doesn't worry much about the distortion of a pleasant sounding amplifier, but he doesn't design to add distortion on top of what the topology naturally produces with the exception of one of the FWs where he installed a knob to switch between positive and negative phase 2nd order distortion. Folks do the same thing with P3 on the complimentary BAGS and F5 too. All of the PL products are very low distortion though.
