Eau Rouge High-Purity Copper Power Cable ER-PS330 1.8M

A new standard for flexible, vibrant, low-distortion power cables

The Eau Rouge ER-PS330 is a power cable constructed with a three-core structure (totaling 4,500 strands), where each ultra-fine φ0.05mm high-purity copper wire is individually coated with urethane insulation and bundled in 1,500 strands per core. This massive conductor cross-section and meticulous insulation minimize signal loss, achieving both musical energy and delicate expressiveness.

The outer sheath uses flexible, easy-to-handle PVC insulation, maintaining the texture and warmth of the sound while offering excellent handling. In addition, the double-shielding structure, composed of a φ0.05mm high-density copper braided shield and a φ0.1mm low-density pure copper braided shield, significantly reduces noise entering the power line, ensuring a quiet background and clear soundstage.

For terminal processing, Eau Rouge uses a proprietary audio-specific solder and a unique plug attachment method that offers better adhesion than traditional crimping. AC plugs and IEC plugs are specially assembled based on wattGATE 5266i / 320i, using "high-purity selected copper" for internal parts and screws.
The ER-PS330 features rich harmonics, natural sound onset, and a smooth energy that envelops the entire musical performance. It is a model that can be considered a new standard for high-end power cables, balancing transparency with sonic depth.

Improved clarity and stability

• The first thing I noticed after switching to this power cable was that the background of the sound became much clearer.
  Perhaps due to the high-purity transmission unique to high-purity copper conductors, the slight muddiness from the power supply disappears, and the transparency of the sound is greatly enhanced. There is a sensation of the sound emerging smoothly from silence, making it easier to perceive details clearly.
  
• The low range also becomes stable, giving the overall sound a solid core.
  With high-quality current being supplied stably, amplifiers and equipment can more easily perform at their true potential, improving low-end control. As a result, the overall sound becomes stronger, with clearer contours.
  

Sound Balance and Musicality

• The tone is extremely neutral, without any tendencies to emphasize certain frequency ranges.
  It extends well from the low to high ranges, allowing you to enjoy the equipment's original sound as it is, leaving a good impression.
  
• The midrange has a decent density, so vocals and acoustic instruments resonate with a natural warmth.
  Rather than adding thickness, it offers a “natural richness” without unnecessary coloration, providing the music as a whole with a sense of credibility.
