@williewonka , that is pretty much all fake science, even this statement:
structure of the wire - i.e. solid vs. stranded
- solid wires can handle a lot more current than stranded wires
Having bought enough wire for experiments, test fixtures, etc. I know to be wrong. Differences between solid and stranded will be perhaps 5%.
Regular copper is used for GHz signals. It does not get any more dynamic than that. Please explain how it could be possible that a conductor formulation, suitable for GHz signal conduction, will struggle with the limited bandwidth coming out of my wall socket. Given all the questionable EMI/RFI issues raised, it should be a significant benefit to be "less dynamic".
A dielectric discussion for a power cable is at best a fantasy distraction. I am not an EE (okay Physics), but it took me about 5 minutes to discover that the source resistance of my AC plug is typically << 1 ohm. If my power cable is 10nF, that is > 10MHz. My AC cord could be used to transmit AM radio with ease. I don't think you could do the math that this matters in any practical fashion for my speaker cable, or even an interconnect. For power cords?
The live and neutral connect together in the transformer or other components in my gear. How does spacing out live and neutral reduce noise? That does not make sense.
This is the problem in the audiophile world. Too many people read things without the background to know there is no way it can be true, and then they tell 10 other audiophiles, and so on, and so on.
