What's odd is that, when they used mikes and speakers with a bandwidth
extended to 100 kHz, the high sampling rate did substantially worse
(23/60). That result is highly counterintuitive, and the authors twist
themselves into pretzels trying to explain it, with no success.


There is a stock answer to this, which may or not be right, but always
needs to be tested. That is, with nonlinear speakers, inaudible
high frequencies can cause audible intermodulation
distortion. This can of course be tested if you have a really really
good high frequency test system (super linear
high frequency microphone and digitizer)
to aim at the speakers.
