We don’t use modern high-end ultra-pure copper or silver wires. We used only old vintage copper wires taken from RCA,klangfilm , Telefunken, Siemens, Philips sound equipment. Stranded wires are composed of different varieties of copper strings on a certain principle that leads to the device’s ability to transmit the subtlest musical nuances. We believe that it is the only way to recover the lost life in recorded music. Just listen!
