Jag har inte JASA här på KI, så jag kan inte ge någon mer info än detta.

Why do you assume that the difference is identical for both channels?
Can you be sure the amplifier damping factor and slew rate capabilities are constant through all four quadrants of operation? And that the inductance/capacitance of speaker cables does not affect that? Don't forget, left and right channels do not necessarily occupy the same quadrant at the same time..
Given the possibility that large acoustic signals can jitter the sound enough to allow 1.5 uSec discrimination, we now are faced with the possibility that 1.5 uSec waveform sloppyness as a result of amp/wire/speaker combinations is audible..
That is over 600 Khz..Way the H##L over anything we can possibly hear..
So, if we can discriminate 1.5 uSec shifts, why do we limit testing to 20Khz?
As I said, the article raises some very important questions.
