Oyaide Electric, with experience gained from a long history of cable design, has developed a reference standard power cable called the "Tunami". The cable is constructed using Oyaide 102 SSC Special Surface Copper.  PCOCC-A wire developed by Furukawa Electric using advanced heat control and extrusion technology. The cable utilizes a 5.5 sq. mm conductor core that is rated up to 30 amps and can take up to 600 volts A/C. This makes it a leader in its class delivering a powerful sound. In addition it has a unique 3 layer shielding system not only to shut out external noise but also to suppress internal noise resulting in a very low noise floor. The combination of advanced and creative technologies delivers the recording artists' every intention along with the delicate atmosphere that surrounds them.


This is an ultra pure single crystal copper originally developed by Professor Ohno. It was then further evolved into PCOCC utilizing a single copper grain wire. This design results in an extremely low level of signal disturbance and loss due to the lack of crystalline borders along the signal path.

Oyaide further refined this process with a highly controlled heating and cooling process and improved furnace management to realize a mirror finish. It is now called PCOCC-A and is the epitome of Japanese craftsmanship.

3-Layer Shielding

It is a fundamental requirement of cable design that they be free from external noise. Oyaide has been a leader in this area with their traditional star-quad structure.

Oyaide has gone a step further with the "Tunami" employing a unique three layer shielding system.

The first layer absorbs the disorders of electromagnetic field formation; the second (carbon) layer is used to absorb the random movement of electrons caused by current fluctuations stored in insulating materials and a third copper foil layer with a drain wire to protect from external noise sources. The drain wire is then connected to ground for perfect shielding.

Insulator:  It is their philosophy at Oyaide to try every possiblity until they have achieved the optimum harmony among the various materials employed in a design. They tested multiple variations in hardness and density of insulating materials to determine which combinations would yield the greatest resonance control. The result was to employ several grades of high polymer polyolefin in the internal structure for maximum benefit.

Oyaide then developed a method for applying the coverings onto the conductors with greater tension to achieve a more uniform and secure fitting.

The Tunami GPX Power Cable is fitted with the now world famous Oyaide P/C-046 Gold / Palladium plugs. Also available with Schuko plugs and affordably priced, it sets a new standard for high end power cable performance.
