As you can see, its all original authentic product and at this price superb value for money. The “TUNAMI” is a powerful, high-speed and dynamic cable of a new generation. The short-pitch stranded PCOCC-A wire which has 5.5sq cross-section area actualizes high-power signal transmission. Its voltage endurance is 600V and maximum amperage is 30A. For noise protection, we specially developed the triple-layered shielding structure. It not only rejects internal and external noise, but also instantaneous spark noise due to vibration.From the deep stillness of TUNAMI, you can even sense the atmosphere of pre-performance of sound source. Since the day of our establishment in 1952, we at Oyaide Electric had opportunities to apply a number of State-of-ART technologies specific to our specialized cable store. Our products reflecting such advantages offer unmatched performance. Moreover, TUNAMI achieved to increase security proved by clearing E.TUNAMI GPX embodies an ideal fusion of State-of-Art technology and craftsmanship. It equipped with P/C-046 special edition plug and connectors which was highly-regarded in the US and Japanese market.PCOCC-APCOCC 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 ? 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.Triple-layered shieldingWe have advocated the importance of noise protection which becomes a defining feature of power cable. Although we accomplished certain results by applying star-quad shielding structure to L/i 50 series, considering customer demands and trends, we pursued producing updated product with a state-of-art technology. For TUNAMI, we developed triple-layered shielding structure.The first layer of this structure converts electromagnetic wave into thermal energy by interfusing electromagnetic insulator. As the second layer, semiconductor layer (carbon) is employed for its characteristic that discharges static electricity without affecting its conductor. A copper foil shielding is set as the third layer to protect the conductor from external noise. Furthermore, drain wires, closely-situated to copper foil shield, make S/N ratio higher by connecting to earth ground.InsulatorAfter the deep analysis for insulator, we selected polymer polyolefin that has different degree of hardness at interior and exterior to prevent negative effect by sympathetic vibration. Moreover, this material has a quarter of permittivity compared to common PVC and we paid careful attention to strengthen the cohesiveness of its insulator and conductor in order to infill random space and maintain a high-quality signal transmission. 102 SSC copper: In 2013 , when Furukawa announced that they would discontinue the production of PCOCC-A copper, Oyaide and others had to consider what they would do to replace it. After deep contemplation of the available options, many of which required unacceptable compromises, Oyaide decided that the best course of action was to make their own proprietary, brand new conductor. They decided to begin with commonly available virgin 99.99% pure copper to insure an uninterrupted supply. At the same time, they decided that their effort should be to create the finest copper ever made for use in high end audio cables. To this end they pulled out all of the stops, going for the most technologically advanced practices and using techniques that had never before been applied to the production of a copper conductor. The result is a new copper called 102 SSC. The 102 portion of the name alludes to the fact that after annealing, the conductivity of the copper is increased by 2.3%, and the SSC stands for Special Surface Copper – the result of final drawing of the strands through natural diamond dies that yields a variation in surface thickness of +/- 1 micron over the entire length of the conductor – a monumental achievement! 3 Element stranding completes the picture, with three different diameters of wire arranged in such a fashion that the spaces between conductors is minimized and the outer diameter of the assembly is stable and thoroughly consistent. Features • Highest Quality Copper Ever • New Advanced Techniques Never before applied to Audio Cable • Proprietary Design • Supply Without Interruption • Conductivity Increased To An Incredible level of 102.3% IACS • Only Pure Virgin Copper Base Material Employed • Mechanical peeling – a very precisely controlled process removes 100% of impurities. • Wire is annealed twice to remove all induced stresses and strains. • ‘In-line’ electric annealing avoids residue of soot left by the commonly used bell type annealing process. • Fine Drawing Process with Natural Diamond Dies • Natural diamond dies yield more uniform volume reduction with reduced stress and improved lubricity compared with synthetic diamond dies • Superior surface structure, with an outer diameter accuracy of ±1?m, far exceeding the ±8?m Japanese standard for conventional copper wires. • 3E [3 Element] stranding, developed and patented by Sanshu Electric Wire, adopted for audio – a new, higher-spec technology. • 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.Triple-layered shieldingWe have advocated the importance of noise protection which becomes a defining feature of power cable.

Here is the importance that Mr. Paul McGowan (PS Audio CEO) places on your power cables:Cables MatterOctober 30, 2018 by Paul McGowanOh boy. I saved this and the next Fact or Fiction for last. This is a real viper pit of a question and those loyal readers of this blog know my answer before I even write it. Of course they matter, but only if we’re a bit open to proving that to ourselves.I suppose we’ll begin with the most reviled of them all, power cables. Tomorrow we’ll tackle signal cables.I am told our company loses credibility amongst the professional engineering crowd whenever we suggest power cables matter to sound quality. And, here’s my answer to that. I am sorry, but that doesn’t change the facts—nor am I incentivized to soften my stance. That the idea power cables matter makes little sense to someone who believes they have the electrical world figured out is something I won’t waste anyone’s time defending. If you firmly believe this to be true—that with your wisdom and knowledge you’re convinced it cannot be true—you should skip today’s post because you’ll be simply wasting your time.The biggest head scratcher for people is this: if there’s several hundred feet of copper wire between the power pole and your equipment, what’s another 6 feet of expensive wire going to matter? As we’ve seen so many times throughout this Fact or Fiction mini-series, how you phrase the question makes all the difference in the world. Posed in the standard way I just described it makes no sense whatsoever. How could it? Let’s try asking it another way. In an AC circuit is the interface between the middle noisy load important? Now, our answer might look a bit different.The notion in most people’s heads is that the powered equipment is at the end of the long copper power chain. This is actually wrong because it’s in the middle of the AC circuit (think of an AC circuit like a loop where the equipment is in the middle, the AC source at the opposite end). Furthermore, our equipment is both inductive and noisy. In fact, chances are good the point where the AC comes out of your home’s wall is the noisiest environment in your home—an environment hostile to good sound. This is why shielding your power cables is so important.Still not convinced?Here is what Nordost say..What is the most important cable in your set up? The most important cable in your sound system is the power cord. At the risk of stripping away any magic from your tunes, the music enjoyed from your hi-fi system is little more than AC power, transformed by components to reproduce a melody. The quality of this reproduction is directly determined by the caliber of power cord which is facilitating this transfer of raw electricity to the equipment. By simply upgrading the AC cable in your set up, the audible difference is remarkable. Unlike other cables, a power cord does not transmit a signal: It conducts AC power. The success of this cable is gauged by its capacity to deliver a sturdy, instantaneous current as well as its ability to reduce the effects of electromagnetic interference (EMI) and radio frequencies (RF) coming from outside sources. A poorly constructed AC cord will actually attract EMI and RF, or noise, to your current, affectively polluting the raw material feeding your system and raising the source impedance of the AC supply. An optimally built power cord, on the other hand, is designed to be less prone to, and reduce, any EMI and RF influences resulting in a faster rise time in the 50/60 Hz cycle. Internal cable shielding has also been connected to the Ground/Earth (Green) cable, to draw any EMI or RF interference from the cable. Nice cables are the jewellery in any Hi-Fi System. ** Please view our other interesting items listed for sale **
