Just to relate a story:

Some years ago people were thinking about deciding on a standard for
FM broadcasts (in terms of frequency response).  Most people (engineering
and technical types) wanted to follow the AM standard, i.e., limit to
5 KHz.  Some people at Bell Labs did some experimentation and came out
with the "radical" limit of 8 KHz (beyond which no difference could be
heard).  Well, the radical fringe had its say, and as you all know FM
standardized on limiting to 15 KHz.

Nowadays, we know that 20 KHz is right.  (Or do we?)

"From transducer to transducer, sound reproduction that's better than
ears."  This is the goal.  When it is achieved, identical will mean
identical -- to all people, in all circumstances.
