RSX ER‑61 Speaker Cables Hear Your Music Come Alive

Our take

At TechX, when we say “benchmark,” we mean it—and the RSX Benchmark ER‑61 speaker cables live up to that name. Designed by legendary audio engineer Roger Skoff (founder of XLO), these cables elevate what’s possible at their price point.

Why they stand apart:

• Exceptional conductor design: They use robust 11+ AWG solid-core copper conductors—some of the heaviest in their class—yet remain surprisingly flexible thanks to a fine Litz‑variant geometry

• Advanced insulation: Employing three distinct low‑κ-factor (low-dielectric constant, high dump‑rate) dielectrics, the ER‑61 minimizes charge storage and distortion for cleaner sound transmission

• Premium connectors: Each cable comes terminated with gold‑plated, non‑magnetic BFA “Z‑style” banana plugs for maximum contact, low resistance, and durability

Listening with ER‑61 cables, even early impressions persist: the sound is immediate—detailed, dynamic, transparent. Positive Feedback Online reviewers and audiophiles highlight how subtle textures emerge, imaging sharpens, and the noise floor recedes—delivering "magic," especially in delicate passages

In short: these cables are engineered to outperform many that cost two to three times more. They're a brilliant match for discerning audiophiles looking for performance, build quality, and value in one package.
