Eau Rouge Pure Silver Solid Speaker Cable ER-SP735

The ultimate potential of Eau Rouge’s pure silver solid ribbon cable

The ER-SP735 is Eau Rouge's flagship speaker cable featuring proprietary high-purity silver ribbon conductors. Its construction ensures minimal phase shift between the conductor's core and surface, allowing the transmission of large currents up to 50A. It delivers stable energy, from subtle nuances to full-on dynamics.

Specially refined 'pure silver' containing gold—a material that maximizes sonic purity

Eau Rouge's pure silver is a special grade refined from mined silver. The trace amount of gold remaining as an impurity stabilizes the silver's crystal structure, resulting in clear transparency, smooth harmonics, and rich texture. This characteristic contributes to the unique sense of silence and natural soundstage that the ER-SP735 provides.

Overwhelming silence created by triple Kapton shielding

For insulation, ultra-high heat polyimide film "Kapton" is used to minimize changes in tone. In addition, the triple-shielded structure thoroughly eliminates external noise, achieving a highly pure spatial depiction with a profound sense of quiet. It carefully renders even fleeting hall tones and subtle reverberations.

High-purity solid silver Y-lugs—clear transmission through unified materials

The terminals use Eau Rouge original pure silver Y-lugs, made from the same material as the conductors. By unifying the materials, audio muddiness from contact points is eliminated, dramatically improving image focus, transparency, and S/N ratio. The combination of fast attack and natural extension is a unique advantage of the pure silver ribbon.

A sound character that pursues 'unexaggerated beauty'

The ER-SP735 sound is free from flashiness or exaggeration.
A soundstage that quietly stands while spreading deeply and majestically.
Smooth harmonics, natural sense of breathing, and realistic air reproduction.
Ideal natural sound for listeners who prioritize tonal purity, such as in classical music, chamber music, jazz, or vocals.

A 'lifelong reference cable' handcrafted by artisans.

All processes are handcrafted by skilled artisans. From the uniformity of materials throughout the cable to structural accuracy and shielding, the design leaves no room for compromise, delivering quality that can serve as the centerpiece of a high-end system for many years.
