Coaxial Cable

"First ever Coaxial wire structure implemented on IEM upgrade cable.“


Our Coaxial wire structure implementation features a central conductor insulated by a dielectric material held in an concentric orientation to a single wire which serves both as an EMI/RFI shield as well as a return path for the circuit.

The implementation involves many careful technical considerations particularly in the aspect of the specific electrical, mechanical, and environmental requirements.

  • Principle

    • Smaller the capacitance larger the impedance, results in higher transmission rate of conductor, thus lower signal attenuation and distortion rate.

    • Theoretically speaking, coaxial structure will result in equal capacitance between conductors, stabilizing signal transmission, and suppresses crosstalk.

  • Layering design

    • Varieties of dielectric material effectively control electrical impedance in accordance to the conductors. This allows stereo separation and clearer sonic resolution.

    • ​Layering design enhance signal transmission with conductors (different conductivity). For example, silver plated copper (low frequency), OCC copper (intermediate frequency), silver plated OCC (high frequency)

  • Data support

    •  Capacitance test report (LCR METER TH2825A)

      • 6.06pf (conductor 1 / conductor 3)

      • 0pf (conductor 1 / conductor 2)

      • 0pf (conductor 2 / conductor 3)​

    • Impedance: ∞

      • This explains least signal attenuation since capacitance is 0.

  • Razor-thin insulation sheath: 0.06mm~0.1mm

    • ​ This determines small capacitance.​
