Gold-plated phono plugs provide
excellent corrosion resistance.
Since RCA-type phono plugs are normally inserted and removed many times, they must be highly resistant to abrasion and provide superior conductivity even after extended use. Another important consideration is the ability to withstand corrosion which can be caused by sulfuric gases and other contamination in the atmosphere.
The thick gold plating of the plugs perfectly fulfills all of these requirements.

- Center conductor core wires are a combination of highly pure oxygen-free copper wires and silver-plated soft copper wires, providing excellent transfer characteristics.
- Center conductors are formed by a combination of two types of highly pure oxygen-free copper wires of different diameter and a silver-plated soft copper wire type with low resistance. The insulation layer consists of polyethylene with high dielectric resistance and foamed polyethylene, resulting in a triple layer configuration, implemented in a dual-core design. Transfer losses as well as DC resistance are minimal.
- Shielding is provided by 192 ultra-fine 0.1 mm high-purity copper wires braided to a high density, plus a layer of aluminum foil tape. This dual approach results in low capacitance and gives extra protection against any form of externally induced noise.
