The second impact of the TUNAMI GPX
The first big wave of the TUNAMI power cable made
a huge impact to the audio scene and it came to be recognized widely
among audiophiles, sound professionals, foreign users and even audio
beginners.For the TUNAMI GPX-R, P/C-004 special edition, equipped with
"Aspirin Snow White" cover, is attached in order to fully extract the
superior potential of TUNAMI power cable. TUNAMI GPX-R is created as a
result of the collaboration between high-performance power cable and
power plug/connector.
TUNAMI is a powerful, high-speed and dynamic power
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 cable 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 GPX-R, you can even sense the atmosphere of pre-performance of sound source.
In addition, we have prepared Schuko plug version, TUNAMI GPX-Re,
for European and Korean users. The big impact of TUNAMI GPX-Re will be
spreading out to overseas.
PCOCC-A
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.

Triple-layered shielding
We 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.

Insulator
After 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.

Connectors (TUNAMI GPX-R, TUNAMI GPX-Re)
The "Aspirin Snow White" outer cover is specially produced
for the TUNAMI GPX-R. It is made from thick Polycarbonate which strength
and hardness attenuate small vibrations at high speed with no added
distortion due to its superior rigidity.
In order to maximize the potential of the TUNAMI power cable,
the contact is modified from phosphor bronze to beryllium copper that
insures the higher level of mechanical integrity and electric
conductivity. And also a combination of platinum and palladium is
employed as well as P/C-004. The thickness of the plating is
optimally-adjusted for the TUNAMI GPX-R.
