A sum of non audible but measurable issues can result in something audible. That's the point.I only want to listen to music. If one wants to look at graphs instead...ok.
The essence for me in the post above is "It's not audible!"
So why?? Perfectly visible satifies me in art. For music my preferences are different. And I am confident that I had missed a lot of fantastic gear if I looked at graphs before. I think in this point we are living in different galaxies. But thanks heaven it is enough space for all of us.
