The final chapter of TUNAMI - The premium interconnect cable with 102SSC



TUNAMI TERZO V2 is the final chapter in the TUNAMI series of audio signal cables. It may be possible to create an audio cable by simply utilizing sensitivity. However, it is not possible to create a universal product.

Especially for Oyaide products, more important factors than experience are required. That is the existence of engineers who put their whole heart and soul into developing audio products. A model created from the spirit of engineers who are passionate about audio and do not compromise in any way.

This is the TUNAMI TERZO V2.


"102SSC" - Oyaide Electric Precision Conductor

  • To avoid impurities as much as possible, only virgin copper that does not contain any recycled copper is used in accordance with JIS C1011.
  • Peeling process is applied to remove 100% of impurities attached to the surface.
  • In order to facilitate the flow of electrical signals through the surface layer of the conductor, the strand is made finer using a natural diamond die to improve the surface smoothness of the strand.
  • The stranded wire is processed with a processing accuracy of ±1μm, far exceeding the standard error tolerance of ±8μm.
  • Two annealing processes are used to eliminate mechanical stress distortions in the strands.
  • Thorough product control of manufacturing control values, maintenance, shipping days, etc. Achieved the highest conductivity of 102.3% IACS.

Patented "3E Stranded" Technology for Twisting Three Different Sizes of Wires Together


The 3E stranded structure is a concentric stranding arrangement of stranded wires in a lump-sum twisted wire conductor, and by arranging three different strand diameters, the stranding arrangement is made denser. By arranging three different strand diameters, the strand arrangement is made denser, enabling a finer conductor structure and improving conductor characteristics.

The strands of these three different conductor diameters are arranged geometrically to minimize the gaps between strands and improve strand density.

Furthermore, the outer diameter of the strands has been downsized to maintain a stable and highly accurate outer diameter, and the cross section after twisting is a perfect circle, an unprecedented conductor structure in the world. This ensures uniform adhesion between the insulator and conductor, eliminating random thickness of the insulation material and making it uniform.

Ultra-thick Conductor Reduces Signal Transmission Loss

The 1.25SQ conductor has the largest diameter among Oyaide's interconnect cables, making it suitable as the flagship of our interconnect cables.

Use of Polymer Polyolefin with Excellent Electrical Characteristics for Insulation to Reduce Signal Loss

Polymer polyolefin with excellent electrical characteristics is used for the insulation coating of the conductor. Compared to ordinary PVC insulation, it has an extremely low dielectric constant of 1/4, which reduces signal loss and produces a less muddy reproduction sound.

The use of polymer polyolefin materials with different hardnesses for the outer and inner cores respectively prevents the effects of resonance on the sound.

The cable is covered with an elegant pearl-white urethane sheath that is highly durable. On the surface of the sheath, "TUNAMI TERZO V2" and "102 SSC" are marked to clearly identify the V2 model.

Triple Layer Shielding to Shut Out Noise

Triple layer shielding is employed: 1st layer: electromagnetic wave absorber, 2nd layer: copper foil, and 3rd layer: horizontally wound shield.

In the first layer, electromagnetic waves caused by magnetic flux disturbance are converted into heat energy by electromagnetic wave absorbers mixed in the compound.

The second layer has a copper tape shield to protect the signal from external noise.

The third layer, a horizontally wound shield, is made of 102 SSC, a precision conductor, with 160 0.12mm wires placed without gaps. This shields out not only external noise, but also internally generated noise and spark noise caused by vibration at a high level.

Experience the ultimate in noise protection and the power of the triple layer shield.
