If the issue is that the dialectric potentially changes the sound, and oxidation of copper potentially changes the sound, wouldn't pure copper wire covered in something to prevent shorting, and oxidation, be ideal?
Ideal? I dunno. That rather presupposes that if the sound is in fact to be changed, it must be a change for the worse.
Is this all really just a numbers game when you get to the bottom of it?
I've always found it curious that often the same people who think that a SET tube amp, with horrendous amounts of distortion, high output impedance, limited frequency response, etc. sounds absolutely fantastic, but when it comes to something like wire, everything changes. The wire needs to be the most conductive. It must be of the highest purity. The dielectric constant of the insulation must be as close to 1 as possible.
Just seems a bit schizophrenic to me.
