For the first time, Acoustune is releasing an upgraded cable "ARX220" with "Sterling Silver" material. The ARX220 is made of genuine sterling silver mixed with OFC copper core, and the most special feature is the extended PE headphone plug, which is supplied with a pair of small ring adapters to match with the traditional PE short connector.

Features:
New metal parts design for the cable body, non-slip metal parts, SUS316 non-magnetic material, greatly reducing oxidation, new core configuration, a mixture of pure silver wire and silver-plated OFC copper wire. This configuration brings wider bipolar extension for all frequency ranges, the OFC copper has a refined and embossed image, especially in the treble extension, which really has a very fine tail, and the grooved steel is made of genuine Japanese PVC, which reduces touch noise and audiophile effect.
