Engineered Hybrid Design

Each core combines multiple high-purity conductor materials with dedicated shielding strands, creating a balanced structure designed for enhanced signal transmission, improved noise isolation, and refined sonic performance.

Precision Assembly & Soldering

All plug and connector terminations are hand-soldered using premium gold-silver solder, ensuring excellent electrical conductivity, stable signal transfer, and long-term reliability.

To further enhance structural integrity, every solder joint is reinforced with UV-cured resin, providing additional protection against oxidation, vibration, and mechanical stress for outstanding durability and consistent performance over years of use.

Material Highlights

1. Six-Conductor Hybrid Design — A Perfect Balance of Materials

Each core combines six premium conductor types, with each material contributing its own sonic advantage to create a seamless full-range performance.

• Rare Earth Copper
  Refined with rare earth elements to reduce impurities, providing a solid foundation with rich mid-bass density and strong control.
• Single Crystal Copper
  Its long single-crystal structure minimizes grain distortion, enabling cleaner signal transmission and exceptional purity.
• Gold-Silver-Palladium (Au/Ag/Pd) Alloy
  A premium blend of three precious metals, delivering smooth, extended highs with refined detail and natural airiness.
• Palladium-Plated Single Crystal Copper
  Enhances transient speed and precision, bringing sharper attack, cleaner decay, and improved control.
• Silver-Plated Single Crystal Copper
  Improves high-frequency transparency, revealing rich overtones and delicate micro-details.
• Gold-Plated Single Crystal Copper
  Adds warmth, texture, and emotional depth to vocals and midrange performance.

2. 11 Flat Shield Strands — Advanced EMI Protection

Each core features 11 flat shielding strands made from Single Crystal Copper, Silver-Plated Single Crystal Copper, and Gold-Plated Single Crystal Copper.

This precision shielding structure effectively reduces EMI/RFI interference, lowers background noise, and creates a cleaner, more spacious soundstage with enhanced detail retrieval.

3. Multi-Layer Plating — Precision Sonic Tuning

Silver, gold, and palladium plating are carefully engineered for both protection and sound optimization.

Each layer enhances conductivity and frequency balance, allowing different materials to work together seamlessly — delivering a refined sound with high resolution, natural tonality, and excellent musicality.
