Advanced Hybrid Conductor Design

The contrasting silver (white jacket) and copper (black jacket) strands are precisely braided together in a distinctive panda-inspired dual-tone design, creating not only a unique visual identity but also an optimized electrical structure.

The combination of single crystal silver and copper provides a balanced sonic character — blending the clarity, speed, and resolution of silver with the warmth, density, and natural musicality of copper.

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.

Why Choose 7N Single Crystal Silver + Copper Hybrid?

The hybrid combination of 7N Single Crystal Silver and 7N Single Crystal Copper achieves an ideal balance between technical performance and musical enjoyment.

• Enhanced Resolution & Transparency：The single crystal silver conductors improve high-frequency extension and micro-detail retrieval, allowing subtle textures, harmonic overtones, and recording ambience to be reproduced with greater clarity.
• Rich Tonality & Natural Timbre：The single crystal copper conductors contribute richer tonal density, smoother midrange texture, and more realistic instrument body, creating a natural and emotionally engaging listening experience.
• Balanced Dynamics & Soundstage：The hybrid conductor design enhances dynamic expression while maintaining excellent coherence across the frequency range. Vocals and instruments are presented with accurate positioning, refined layering, and a spacious, well-organized soundstage.
