When I got my S5's home an immediate observation was that my music sounded more different from each other than it had in past systems. My speakers/system was not adding its own "sound" to all the material to the degrees it had past. This is a partial definition of neutrality to me. I don't equate "clinical" with neutrality.
Also, I believe measurements have a place in the evaluation of equipment, but too many of us want black and white definiteness in a decidedly gray world of sound.
I absolutely agree. Neutrality should not "add to....or subtract" from the original signal it is attempting to reproduce. Neutrality should not equate sterile, thin, hyper detailed, or clinical.
