They are directional just ask Nicola Tesla’s grandson , Ted Denney
from Synergistic search , he is always boasting claims on 1 Million volt Tesla coil ,I asked to see proof and white papers to substantiate ,he hung up on me 3 years ago . Even if the wire is drawn in that direction , within 24 hours if reversed it will sound the same. Thst being said purity of Copper silver does count
like 7-9s pure OCC copper is drawn in a nitrogen atmosphere when cooling and the pours like bumps in a road instead of 1000s per yard ,to a few hundred it’s a much more linear signal path.
as well as type of dielectric ,speed of signal ,and connectors,brass most use ,are vastly inferior vs Silver plater pure Copper connectors 3x lower resistance, as well as 3x better conductor .
certain things count, in absolute terms. I have found coating the contacts ,and AC cables with High fidelity audio cables 1260-3D contact enhancer fills the voids or in the pours in the metal with their super conductor formula ,
for $350 it’s a exceptional product ,and by far the best signal enhancement product I have found ,and I have tried most everything available the last 5 years.
