Interconnect HS-101GP (Golden Performance) of the Japanese company Harmonix has a directional structure. It is made from directionally extended PCOCC copper (like higher models of Furutech, Oyaide and the whole offering of Acrolink) and is equipped in an independent shielding system. The contacts are made from PCOCC copper, gold plated and then rhodium plated. This looks awesome. As it can be read – in the otherwise unfortunately sparse – company materials, the main concern while developing the cables was to achieve lowest capacitance possible.
