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.

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.
Traditional two-core shielded structure
We use a 2-core shielded traditional design, with both conductors placed evenly spaced to have an impedance of 120Ω.
At the same time, precision conductor 102SSC is used as the shielding layer, and the braiding rate of 80% consists of 8 pairs of 24 braided shielding layers of 0.12 mm.
Oyaide special halogen-free sheath
The sheath is made of halogen-free polyolefin material, which is anti-aging, wear-resistant, chemical-resistant, low-smoke, halogen-free, and non-toxic.
PA-02 TR V2 special gold-plated RCA plug
The rhodium-plated brass tube connector is an RCA plug designed specifically for the PA-02 TR V2 . The metal parts are made of copper tubes, and the contacts are also plated with 24K gold to prevent contact corrosion.
In addition, low dielectric constant materials are used as internal insulation and reduce transmission losses, and the most perfect quality is achieved through fine drum polishing, chrome plating and final mirror polishing.
Use suitable special solder "SS-47"
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.
