Custom Made Stereo 3.5mm to Stereo 3.5mm Using Oyaide PA-02 PCOCC Cable.

I have just made a length of interconnect with two high spec Canare 3.5 mm stereo jacks on each end and a 1 foot length of Oyaide Electric PA-02 PCOCC Cable. This is used as interconnect between headphone amplifiers and source equipment such as CD player or MP-4 player.

Oyaide PA-02 Cable Details:


PCOCC copper is a material that includes very few impurities and insures very low levels of signal disturbance. Because of its low incidence of grain boundaries, the signal passes without impediment or distortion. Heating and cooling the PCOCC wire under controlled circumstances yields a densely re-crystallized, highly pure structure called a μ conductor. The resulting product with a mirror finish applied is called PCOCC-A copper. This highly advanced product is made possible by the combined application of high technology and traditional Japanese craftsmanship.


For PA-02, we employed traditional balanced type shield wire structure and triple-layered inverted concentric structure which insures maximum density and uniformity of wire structure and infilling of internal space and preventing deformation among the wires.

For its insulation material, we employed formed polypropylene which is a low-dielectric material and insures reduction of loss of signal transmission.

Outer sheath

In addition to PCOCC-A conductor, the halogen-free sheath developed specifically for audio applications is applied for PA-02 with assistance of Furukawa Electric. This RoHS compliant sheath has excellent vibration damping property and high transmitting capability by ideal compounding ratio of materials.
