Again, this is all about the minimizing artifacts of filters within the audible range below 20k. Aliasing is especially troubling because it masks detail in the upper midrange as opposed to being an identifiable distortion. I've literally heard brushes on a snare drum disappear.
Hi Bob,

If I might add to this, an often neglected part of the sampling theorem is that it relies on continuous signals, they are band limited but also infinite in length.

In practice you need a sufficient number of samples for accurate time domain reconstruction. The consequence is a sine wave can get by with lower sample rates, transient events require higher rates.

So it's not entirely about the filters, though they certainly are crucially important.
