Measurements are steady state tones in laboratory conditions and music is ever changing and ever evolving so measurements are for the equipment to meet certain criteria but the true test is to play dynamic music to really discover the true gems of the industry and they won't be the ones everyone talks about.
Why is science just a starting point and not an end point?
Measurements are useful to verify specifications and identify any underlying issues that might be a concern. Test tones are used to show how equipment performs below audible levels but how music performs at listening levels is the deciding criteria. In that regard science fails miserably.
