I think when 44.1 kHz was selected for the sample rate (I still don't know how they decided on such an oddball frequency), there was too much faith in the Nyquist/Shannon Sampling Theorem, which unfortunately only holds true for steady state signals. But music isn't steady state. The theorem falls down with non-steady state "transient" events, where "ringing" is introduced in the time domain (using the so-called "perfect" sinc filter). So the "perfect" sound couldn't truly be perfect.I've had debates with theoretical engineers who thought I was a crackpot for questioning this theorem for audio application..... They treated the time domain issues as a strawman argument.
