Default AES article: hi-rez more like analog?

What's odd is that, when they used mikes and speakers with a bandwidth

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.


But wouldn't these inaudible frequencies be present in the original
analog feed, as well as the high-sampling rate digital conversion?
That should make the two sound *more* similar, and less like the 44.1
conversion, which would filter those frequencies out before they
reached the speakers.
