Best Sounding Speaker Cables?

Which all distill down to LCR and R is mostly irrelevant

The problem these are all variable.  They are not constant.

LCR is spatially variable.  To some degree, LCR is also dependent on the input stimulus.  To say LCR per foot is just too much of a blasphemy.  

LCR is dynamic to the level it impacts musical program.

I am not sure what you meant.  But inductors and capacitors can become non-linear if the applied stimulus will exceed the rating parameters.

^^^ Most LCR meters measure LCR of a cable as a per foot metric.  But in a cable the LCR is a distributed phenomenal so it's not like the entire cable is one big inductor or capacitor.  The inductance or capacitance can vary along the length of a cable.  I expect a good cable to have very little variance, whereas in cheap cable the variance can be relatively larger.

If you have a large variation in LCR, you could have reflection of the energy along the length of the cable.
