Precision Conductor "102 SSC"

  • The cable part has precision conductor ''102SSC'' wire.
  • To avoid impurities as much as possible, use pure copper without any recycled copper.
  • Remove 100% of impurities attached to the surface.
  • In order to make the signal transmission on the conductor surface smoother, natural diamond molds are used to thin the wires to improve the surface smoothness of the wires.
  • The processing accuracy of fine lines is ±1μm, which is much lower than the standard error of ±8μm.
  • In the stranding process, a high-density multipath conductor 3E stranded structure (patented) is used to increase density and roundness and stabilize electrical characteristics.
  • The mechanical stress and strain of the wire are eliminated by two annealings.
  • More complete product management

Patented technology "3E twisting" can twist wires of three different thicknesses

The 3E twisted structure is a concentric twisted array structure of collectively twisted conductors. By arranging three different wire diameters,
Densifying the stranded wire array reduces the diameter of the conductor structure and improves the conductor characteristic values.
The geometric arrangement of strands of these three different conductor diameters reduces the gaps between strands and improves conductor density.
As the outer diameter of the stranded wire decreases, a stable and high-precision wire body is maintained.

Use insulating materials with excellent electrical properties

High molecular weight polyolefins with excellent electrical properties are used in insulating coatings for conductors. Compared with general PVC insulation,
The dielectric constant can show an extremely low 1/4 value, reducing signal loss.
In addition, by using a different polymer polyolefin material for the exterior and interior, the impact of resonance on sound can be prevented.

Three layers of shielding to block noise

Layer 1: Electromagnetic wave absorber,
Layer 2: Copper foil,

Layer 3: Use horizontal winding to surround the copper foil. By mixing the electromagnetic wave absorber into the compound, in the first layer, when the current flows through the cable, a weak vibration will be generated, and the statically charged material will be discharged due to the vibration. A copper tape shield is provided on the second layer to protect the signal from external noise. In addition, the third layer of shielding uses precision conductor 102 SSC, and is designed with 160 0.12mm wires, which are tightly packed together without gaps.


For RCA plugs, the contacts are made of phosphor bronze, and the outer layer of the contacts is plated with platinum + rhodium to increase durability. In addition to increasing the tightness after insertion, the spiral latch can also control the vibration of the body and shell.
The main part of the shell is made of brass plated with hard chrome, showing a very high-end chrome plating effect.

SS-47 special solder

The plugs and cables are soldered using audio-specific "SS-47". "SS-47" uses 99.993% (4N) high-purity tin.
Silver and copper are mixed to improve conductivity. Ordinary alloy solder, the synthesis ratio of silver is 3~3.5%,
However, SS-47 uses up to "4.7%" silver, which greatly improves the conductivity.
Maximize the performance of the sound.
