Perfectly valid question re highly polished conductors. Here’s what Audioquest says, this paragraph refers to their Dragon High Current Power Cord.
HIGH PURITY CONDUCTORS - PERFECT-SURFACE SILVER (PSS)Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest’s highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
Lizzie, you said you thought they were polished in a non oxygen atmosphere. Do you mean like on Pluto?
