Effective October 20th, 2025 RSX Cables are temporarily unavailable due to production delays.
BENCHMARK ER-31 Phono Cables
BENCHMARK Phono Cables feature high-purity oxygen-free copper conductors with multiple low-Kappa factor, high “dump rate” dielectrics, and provide full coverage bi-metallic shielding to protect the signal from even the lowest-output phono cartridges. They are available either with gold-plated ultra-low-mass RCA connectors for tight contact and the lowest possible self-inductance, or with a combination of those same RCA connectors and a best quality gold-plated, Teflon dielectric, straight DIN connector.
The BENCHMARK Series is RSX’s highest value line. While still retaining the hand termination of all other RSX products, the cable portion of every BENCHMARK cable Is specifically designed by Roger Skoff to be custom machine manufactured. This saves hours of hand labor per cable as compared to RSX’s other lines and RSX uses the savings to buy better materials and technologies to provide truly remarkable performance at its very modest price point. The “ER” in all BENCHMARK product names stands for Enhanced Resolution and that’s what it delivers.
