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.

Audio cables must fulfill a number of important requirements. They must have minimum transmission losses, not introduce any sonic character of their own, and bring out the sonic and musical qualities of connected equipment to the fullest. Audio cables from Accuphase employ the most up-to-date sophisticated technology to fulfill these goals. As a result of intensive research into conductor and insulation materials as well as cable construction principles, combined with extensive series of listening tests, we proudly present this latest high-quality cable that introduces virtually no losses and that allows the music to emerge in all its refined glory.
- SR series cable features an 8-core multi-hybrid configuration. Center conductor consists of two sets of four different copper wires, including an extra thick 7N (99.99999%) ultra pure copper wire with 0.9 mm diameter.
- Center conductor dielectric employs polyethylene with low inductivity and high insulation resistance, to reduce stray capacitance between the conductors.
- Braided outer shield is a dual-shield type combining 192 ultra-fine 0.1 mm diameter soft copper wires with aluminum foil tape. This design reliably shuts out any external noise.
