Why is science just a starting point and not an end point?

There is no measuring device as sensitive as the human ear, among other things.

In that regard science fails miserably.

Science dont fail at all...Pseudo scientist fail....

Only those not using their own ears at  the endpoint fail...Science do what science did the best: give us great engineering possibilities...

No problem I don't listen to Bach. 

Science explains the music and the gear completely. Don’t be silly. It’s the people or the listeners that defy science. 

There is no measuring device as sensitive as the human ear, among other things.

I will say this in another way...because it is not "true" written  like this...

The ears is "sensible" to meaning in sound....The ears is less sensible than some tool for this unidimensional accuracy by numbers, but for accuracy of meaning, which is multidimensional, nothing replace the ears...

Any tool live in ONE dimension which is the dimension of his use and parameters of his application...

The ears live in many dimension at the same time, which are all linked together by "meaning" for our consciousness....
