WBT, Germany WBT began making RCA plugs in 1985 – with the aim of creating mechanically robust plugs with an innovative design as an alternative to the various unreliable shaped sheet metal parts that ruled the audio market at the time. They are now the World leaders.

Improves further the overall balance tone and definition, add more space and airiness we like it. Its not night and day but certainly adds more overall refinement, its the icing on the cake.
The UP OCC process for refining copper was developed and patented by Professor Ohno of the Chiba Institute of Technology in Japan. The licensed to use this manufacturing process is incredibly popular for the production of wire and cable products for the audio/video industry. UP OCC stands for Ultra-Pure, Ohno Continuous Casting. In conventional processing, hot molten copper is poured into a cooled mold for extrusion, resulting in multiple, fractionated crystal structure. While the copper may be “pure” in the sense of measuring gas impurities in the copper in comparison to standard copper refining techniques. Oxygen Free Copper (OFC) has undesirable effects that lead many to use more expensive materials such as silver for their conductive strands. As developed for A/V cable use, the OCC process utilizes a heated mold for casting and extruding, with cooling taking place in a separate process. The result is a larger crystal size and increased purity that approaches the 6N, 99.9998%!
