You can look at current distribution, electron deposition on insulation, IMD, THD, phase shift, and the best part is, all of those specification, along with R, C, are relative to frequency at which the signal is measured at that given moment. The test can be done, but boy is it tedious. And also remember your instrument needs to be at least as sensitive or more sensitive to the micro changes in the difference of those parameters. The ability to look at electron movement and electron deposition within a cable is certainly beyond the capability of many cable makers. Remember electron don't actually move themselves.
The design of cable is very much, within an engineering perspective, an applied quantum mechanics problem.
Science can explain all those 'I can' or 'I can't' argument, its whether anyone wants to spend the $$ and to such extreme length to explain it. With the barrier of testing sitting at the stratosphere of $$$ needed, most manufacturer relies on their 'golden ear' to determine the sound of one cable.
You can very much make an analogy to chocolate taster, one of the most important position, at the major Belgium chocolate manufacturer. Chocolate tasters are by definition, hired to taste, and determine whether the chocolate taste is good or not. It is entirely possible to analysize the composition of the chocolate via good chemical engineering, but it sure is quicker to have the tester tell you, the sample doesn't taste right and need to add few more grams of coco powder to the mix.
