"An electrical study of single-ended analog interconnectcables"

I actually took a look at the paper... he goes to great lengths to find any difference in the cable that is not obviously outside of human perception, but does not seem to connect it to audio output at any point.

I think the bottom line is he asserts decay times from certain effects are around 1 microsecond long, and therefore possibly audible. He does not attempt to connect anything he measured to anything he or anyone else heard, from what I can tell.

And I think you can see how motivated his reasoning is:

While the nominal reactive time constants may possibly be too short (<100 ns) for discernibility

100 nanoseconds MAY POSSIBLY be too short for discernibility? Buddy.

Sound travels 34 mircometers in this amount of time. This is how far your skin moves due to blood moving in your veins. If this time difference was discernible, we would be constantly aware, just by listening, of not being able to hold perfectly still even when our heads were literally clamped in a vise. I think doppler distortion would be considered the worst kind of distortion because we could easily, blatantly hear the delay when the midrange cone moved inward. Speaker cones introduce delays 100+ times greater than this. Just... whatever, man.

No transducer exists that can introduce smaller delays, but sure... it's the 6-inch RCA cable that's screwing up your listening session.

Anything to avoid admitting sighted listening produces the differences you hear, I guess.

Given good connectors (ones that make good center and shield contact) and relatively high quality cable (low capacitance etc) the most important quality of unbalanced cables is the resistance of the shield. After all it is connecting the signal and power returns between the pieces of equipment. It came about back in the day of "hifi" consoles (are you old enough to remember?) where the turntable, radio and amplifier (and speakers) were in the same cabinet and probably shared a common power supply
 
Yep, for line level RCA interconnects, low end-to-end resistance of the shield is the most important quality of the cable.
And maybe good connectors (ones that make good center and shield contact) are even more important.
