I have probably spent over 20 years squabbling on forums about the subject of cables and I decided a couple of years ago I wouldn't do any more of it and kept my head down when the subject was being debated.
I realised that the naysayers were using non-scientific terminology as part of their stupid and illogical arguments, things like "expectation bias" and "placebo" which are utterly irrelevant in this context, then saying that LCR parameters explains everything so it is impossible to state that cables with equal LCR parameters will sound any different. The worst of the lot is the statement that double blind tests are the final arbiter, but even that is riddled with serious flaws amd cannot be relied upon either. The naysayers have stuck to their intransigent positions and I cannot be arsed any more to get them to see how ridiculous their pompous stances really are.
LCR measurements as we know them are incredibly crude and primitive, especially so when the majority of measurements are taken in static conditions, whereas music is constantly changing in frequency, amplitude, voltage and current, which all affects those LCR parameters. That is not where the answer lies.
Metallurgy does play a significant role though and if we subdivide the two main materials into their respective traits of copper wire versus silver wire, then look at their purities and the way the metal is fabricated and treated, then it gets a lot more complicated. Then add into that the way the wires are insulated and it gets even more complex. The naysayers joke that silver wire is a brighter colour than copper and therefore will produce a "brighter" sound which does have a tiny grain of truth, but that too is throwing the baby out with the bath water by saying that there is a difference between the two metals, yet at the same time denying that they do have sonic differences!
I'm going to stop there for the moment as I can feel my blood pressure rising already which isn't any good for me, but I will return to this thread later.
