It's Simple

good read.  Unfortunately it is not as simple as LRC.  Faithfulness to phase and amplitude is important and aspects of LRC are important, especially reactive LRC relative to its affect on phase and amplitude. There are probably other factors that are important, such as IMD, etc, and some we do not know about or how to measure them.

simple, nope, not even close but once someone works it all out then it is probably simple.  until then...

Proximity Effect, Skin Effect, Purity, Metal, Plating, Insulation Dielectric, Fatigue, etc.

yes, these and others are probably as important as LRC, especially R, although changing R changes the reactive LRC. 

definitely not as simple as just LRC especially when, as indicated, 75mm of wire, strategically placed, can completely change the sound by an enormous amount. 

once someone works it all out then it is probably simple - until then - although building a bridge is usually not simple yet we see them everywhere.  Some bridges can be very simple but do they really do the job, in some cases sufficiently so and in other cases not so... perhaps there are too many variables, and too many assumptions, to allow over simplification, although like bridges some simplification is possible and sufficient.
