I already bought this cable in France for a price more than double where my interest in this article. The cable was received well Norstone W150 but it was nothing but silver just by pure copper. There are two very similar references in Norstone: * Normal W150 whose sheath is white (hence the W!) And there is the C150 which is transparent sheath (C = clear) * The W150 also silver with white sheath, copper conductor is plated. Obviously the silver is much more expensive but to have tested both, the bonus is still slightly visible which makes it necessary for the high-end equipment "audiophile" and uninteresting on the home theater or audio medium range.
