The plot shows a log scale on the y-axis and a linear scale on the X-axis, which is kind of misleading, since the amount of HD actually goes down dramatically with incremental increases in NFB. Can we really hear 4th, 5th, and 6th order HD? I would guess not so much. And maybe 4th and 6th order are not so bad anyway. Therefore if you confine your concerns to 2nd and 3rd order HD, you could use these data to argue FOR the use of GNFB. For example, at around 18-20db of NFB, the 2nd is down 10-fold, and the 3rd is not worse than the initial (at 0 db NFB) amount of 3rd.Having said this, I am no advocate of using lots of NFB, either.
