You kind of have a point.
Some get hysteric about 0.999% purity in cooper wire vs. a 0.9999%! At a time some way bigger issues are hidden below the cover of our equipment.
None is treated for directionality, cryogenic, skin effect or high purity cooper. They are all standard wires and PCBs.
Most so called hi-end cables, pretentiously use superior materials and look are practically poor conductors for the task of most amplifiers (thin wires). Those are not a match and never been calculated for the task. My idea, of having the optimum conductor (calculated) from materials that are not so pretentious or superior (by purity or any other crap), do the job and get fantastic results. It is time to weak up and faces this reality.
