I think that he try to say is that the inability to reproduce anything but "pure" sinewave at 20KHz is one of the culprit of "digital sound".But it only produces a pure sinewave at 20kHz if the signal is a pure sinewave or the fundamental of the signal you're reproducing is at 20kHz. What the hell has a fundamental of 20kHz save perhaps for a synth?
The waveform of music is way-off of any ressemblance to a sinewave. So, the microphone may have captured higher than 20KHz not sinewave and then, the only thing you get in analog is sine wave, which is far from the original signal.
Again, you'd only get a 20kHz sinewave if the original signal were a sinewave or the original signal was of something playing a note with a 20kHz fundamental. For everything else, you wouldn't get a sinewave.
