Cardas 1 x 21.5awg Series Coaxial Interconnect Cable

Cardas 1 x 21.5awg Series Co-Axial, Copper Litz Wire Conductor, Interconnect CableDuring the mid eighties, there was a shortage of ultra pure, ultra soft copper in the United States and the consistency of costly imported copper was poor, so Cardas Audio began manufacturing their own copper conductors. Other manufacturers, using quality materials and carefully monitoring standard drawing processes, produced a good conductor, but not a great one. Conventional manufacturing starts with pure copper, but during the drawing process, adds impurities, hardens and oxidizes the copper. Cardas developed a method to actually purify and super anneal the conductor during manufacture.Starting with pure electrolytic bar copper with no recycled content, their proprietary process reduces, refines, draws, polishes and anneals the conductor. Conventional copper is annealed only after the final drawing stage, using a quick, electrical current process called Resistance Ann
