What's that say about the known and much larger non-linear
effects in speakers that we all know and love? I think the
guys that claim to hear these miniscule phase and dither
differences played back through the best of the available
speakers are blowing smoke...

They argue about what they hear as a function of a couple of
degrees of phase shift at Nyquist and the kind of dither
applied to get to 24 bits!

I notice that the one thing they are too totally polite to
ever do is question each other's "golden" ears despite the
differences among themselves in what they hear. Feet of
clay all around, perhaps.

It was my annoyance and disbelief in all of this that
motivated me to look hard at Doppler distortion and find a
way to quantify it. The rest, as they say, is history. :-)

Actually, I am quite happy to find that it exists, if not
for the usual reasons given, because of this original
motivation.
