@tubegeek,
"While there is an apparent technological advancement in the materials used to make cables, it’s still all comes down to capacitance, inductance, impedance, and DCR"
Hopefully, the above is a statement we can all agree upon. The science of cables.
As the OP asked,
"If there were measurements that correlated to what you hear, I think more people would be interested in cables."
As far as I know, nothing beats high purity OFC. Not in performance, not in sound, nor in price.
OFC is ridiculously under priced for what you are getting. 99.99% purity.
"Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high conductivity
copper alloys that have been
electrolytically refined to reduce the level of
oxygen to .001% or below.
[1][2]Use in home audio
The high-end speaker wire industry markets oxygen-free copper as having enhanced conductivity or other electrical properties that are supposedly advantageous to audio signal transmission. In fact, conductivity specifications for common C11000 (ETP) and higher-cost C10200 Oxygen-Free (OF) coppers are identical;[12] and even the much more expensive C10100 has only a one percent higher conductivity—insignificant in audio applications.[12]
OFC is nevertheless sold for both audio and video signals in audio playback systems and home cinema.[12]"
