Excellence Audio Cable XLR 0.75m. The highly elaborate, double-symmetrical design of the Excellence stereo audio cable, combined with double shielding, provides the most effective protection for sensitive audio signals and minimizes external interference to a minimum. The silver-plated conductors transport the analog music signal precisely and enable a dynamic and crystal-clear sound, especially with high-resolution audio formats. Optimal contact and minimal transition resistances are guaranteed by the solid, 24k gold-plated connectors.
