We've some hot new news from Oyaide Japan, actually we've known for sometime now, but Oyaide have just released the press announcement of their exciting new range of cables.
This is the highest quality copper ever offered from Oyaide and uses new advanced techniques never before applied to audio cable. This proprietary design includes a wire drawing process to increase conductivity "to an incredible level of 102.3% IACS". Oyaide is using only pure virgin copper base material and then adds a special mechanical peeling, which is a very precisely controlled process and removes 100% of impurities. The wire is annealed twice to remove all induced stresses and strains whilst 'in-line' electric annealing avoids residue of soot left by the commonly used bell type annealing process. Their new technique includes a fine drawing process with natural diamond dies that yield a more uniform volume reduction with reduced stress and improved lubricity compared with synthetic diamond dies says Oyaide. A superior surface structure, with an outer diameter accuracy of +/-1μm, far exceeds the +/-8μm Japanese standard for conventional copper wires. The wire strands to eventually manufacture a finished cable is formed in 3E (3 Element) stranding, developed and patented by Sanshu Electric Wire, and have been adopted for audio to achieve a new, higher-spec. 3E stranding combines strands of three different diameters to increase the density of the wire by decreasing the spaces between strands. This results in a smaller outer diameter than the same gauge wire made with identical individual strands, plus a more accurate, stable and perfectly circular cross section. V2 (Version 2) 102 SSC cables are now available.
