I wasn't talking about a "good system", whether you're referring to D/A

ears, I lowpass everything to 11KHz because I can't really hear higher than
that and why waste all those bits when I can cram 20 hours onto a CD.

While I
consider this to be an academic discussion since I have high
frequency hearing loss, it does seem to me that with a sample rate of
44.1KHz, a 22.04KHz sine wave is indistinguishable from a 22.04KHz
square wave despite being below the Nyquist frequency,
In any good system, both
are going to be silence, as they've been
entirely lowpassed away.
