@rooze that last link you posted talks about the main measurable parameters having the most pronounced effect.
Conclusion #1 – A cable’s electrical properties can be measured. In doing so we find there are a number of significant differences between different cables designed to do the same job. These measurable differences in the electrical properties of cables can be correlated directly to the differences we hear in the sonic profiles of cables. [more later]
Therefore measurable differences in the electrical properties of audio cables can and do affect how the music sounds and in a predictable way.
We go right from conclusion #1, to finding that most “magical cables” do not come with specifications on their main electrical parameters.
They are mostly sold as “Just listen to them”.
If we were to know that some specific capacitance and inductance helps a specific system, then it gets easier to move from that cable to a “slightly” different sound, in predicable ways.
Currently it is more like a Pentecostal revival, where one reaches into a bag of snakes, and prays like hell that the outcome is not going to go too badly.
(Pulling out the snake shaped cable that hopefully tames their system… and if it is directional, then they have hopefully grabbed it near the arrow behind the head.)
If we knew the basic specs, then things like skin effect and dielectric biasing can be considered when we know that cable A and cable B are largely similar.
