Today the tradition lives on. Japan produces copper of an extra-ordinary purity (99.999999%) and the PCOCC (Pure Crystal Ohno Continuous Casting) copper developed by Dr. Ohno of Chine Institute of Technology. This revolutionary copper casting process forms copper crystals continuously without breaks, whereas the conventional process does not.
The technology was applied for development of HRMCS (Helical Round Multi Conductor System) cables.
Ortofon Japan Co, Ltd. in cooperation with a high quality audio cable maker succeeded in developing unprecedented ultrahigh performance cables. After countless listening to a wide range of music, HRMCS was selected as the best performer among numerous configurations of test cables.
The unique feature of HRMCS cable is a single core wire that is surrounded helically by wires of different sizes in a cylindrical shape. This arrangement completely isolates the positive and negative sides, maintaining the ideal interface distance between the core and the surrounding wire strands. This configuration boosts the efficiency of air-insulation and cancels out the electro-magnetic induction.
The HRMC cables are truly superb performers that provides high fidelity signal transmission, wider dynamic range and remarkably open and detailed high frequency reproduction.
The HRMC cables are available in Pemium Series and Reference Series. Our highest fidelity cables are constructed from 7N purity silver. Even with silver having the highest conductivity of any metal on earth, Ortofon’s stringent manufacturing process results in a purity increase from 3N (99.9%) to 7N (99.99999%) grade. The resulting product is not only 1,000 times purer than 3N but also has the oxygen content removed to a molecular level.
