Discover the Ultimate in Audio Purity

In the relentless pursuit of perfect sound, audiophiles around the world demand components that deliver absolute clarity, precision, and musical truth. At the heart of that pursuit lies conductor purity — and nothing embodies that ideal better than Ohno Continuous Cast (OCC) single-crystal silver and copper.

Used in our finest interconnects and tonearm cables, these materials represent the pinnacle of audio metallurgy, engineered for world-class systems from Linn, SME, Rega, Naim, Chord, and beyond.

What Is Ohno Continuous Cast (OCC) Technology?

Developed in the 1980s by Professor Atsumi Ohno, OCC technology revolutionized conductor manufacturing. Unlike conventional casting methods, which create metals full of microscopic grain boundaries, the OCC process slowly cools molten metal under precisely controlled conditions to produce a single, continuous crystal structure.

This virtually eliminates impurities and crystalline barriers — resulting in a conductor with exceptionally low resistance, minimal signal distortion, and superior signal integrity across the audio spectrum.

The Superiority of Single-Crystal Silver and Copper

1. OCC Single-Crystal Silver

• Ultimate Conductivity – Silver is the most conductive metal known, offering near-zero signal loss.
• Unrivalled Clarity – The single-crystal structure ensures an unbroken signal path, producing breathtaking transparency, detail, and dynamics.
• Long-Term Stability – Exceptional resistance to oxidation guarantees enduring performance and tonal consistency.

2. OCC Single-Crystal Copper

• Exceptional Purity – Although slightly less conductive than silver, OCC copper far outperforms traditional multi-grain copper conductors.
• Rich, Natural Tone – Copper’s inherent warmth and weight create a beautifully balanced and musical sound signature.
• Outstanding Value – A more cost-effective option that still achieves reference-level performance.

Why It Matters

When music passes through a cable made from OCC single-crystal conductors, there are no microscopic barriers to impede the flow of electrons. The signal travels in a smoother, more coherent path — preserving every nuance, texture, and harmonic detail of the original recording.

The result is a more open soundstage, greater tonal realism, and a profound sense of musical presence — qualities that define the Gothic Audio experience.
