Besides this being "the topic / thread from hell", here are some more comments.
7, if electrical measurements "dictate" what a cable sounds like, why don't people just buy zip cord and "duplicate" their "favorite" cables measurements via electrical components ? It would be WAY cheaper, wouldn't it ? After all, you could simply measure the characteristics of a specific cable that you liked in your system and go from there. Once you factored in the amount of inductance in the "el cheapo" zip cord ( which you forgot to mention ), you could then simply add series resistance, capacitors, inductors, etc.... as needed. Why don't people do this ? Because it doesn't work !!!
The bottom line is that "lumped sums" do NOT equal the sonic characteristics even if they DO match electrical characteristics of the other cable. If you think that the differences between having electrical values "spread" amongst the cables or "lumped" is not measurable, detectable or audible, you need to do some checking. Borrow or find access to a TDR ( Time Domain Reflectometer ) and see for yourself. Slight kinks in cables are QUITE measurable in terms of impedance bumps, voltage to current ratios, velocity factors, etc...
Just as cables DO alter the sonics of a system, it would be nothing less than SILLY to NOT take them into consideration when building a "system". After all, ALL of the signal IS passing through the speaker cables along with the majority of other cabling in the system.
There would be NO questions asked about any of this stuff if we were talking about building a high performance car. Since most every aspect of an auto's performance ( from BSFC to horsepower / torque curves, to acceleration to braking, etc... ) can all be verified with hard numbers, we would be left with nothing "subjective" to deal with other than how the car "feels" or what our personal preferences were in terms of "ergonomics".
Unfortunately, audio is almost 100% subjective due to the various electrical characteristics involved and the differences in how we hear as individuals. This is true REGARDLESS of how something measures on the bench. If you haven't seen "unexplainable" differences between components that measure similar in identical installations, you've spent WAY too much time in the books, theory and "drawing board" and WAY too little time with hands on experience.
