Material Science: The UPOCC Advantage

What is UPOCC Copper?

UPOCC (Ultra-Pure Ohno Continuous Cast) copper represents the highest grade of copper available for audio applications. Developed by Professor Ohno of Chiba Institute of Technology, this specialized casting process creates copper with unique properties:

• Single Crystal Structure – Unlike standard OFC copper which contains thousands of grain boundaries per meter, UPOCC copper features continuous crystal structure with virtually no boundaries
• 99.9999% Purity (6N) – Extreme purity eliminates impurities that can cause signal degradation
• Superior Conductivity – Continuous crystal structure allows electrons to flow with minimal resistance
• Reduced Distortion – Elimination of grain boundaries prevents micro-reflections that can color the sound

Why 6N Matters

Copper purity levels and their typical applications:

• 4N (99.99%) – Standard OFC copper, entry-level audio cables
• 5N (99.999%) – High-purity copper, mid-tier audio cables
• 6N (99.9999%) – Ultra-pure copper, flagship audio cables
• 7N+ (99.99999%+) – Extreme purity, diminishing returns for most applications

The ORCA's 6N UPOCC copper represents the sweet spot where measurable performance improvements justify the investment.

Advanced Litz Construction

112-Core Configuration

The ORCA features 112 individually insulated 0.1mm copper strands per wire, arranged in a precision Litz weave. This sophisticated construction provides multiple benefits:

• Reduced Skin Effect – At audio frequencies, current tends to flow on the surface of conductors. Multiple small strands provide more surface area than a single large conductor, reducing resistance
• Enhanced Flexibility – Many small strands bend more easily than fewer large strands, creating a supple, comfortable cable
• Improved Durability – If individual strands break, the remaining strands maintain signal integrity
• Optimal Signal Transmission – Litz weave ensures each strand carries equal current, maximizing efficiency

4-Wire 24AWG Design

The ORCA uses four separate wires (left+, left-, right+, right-) in 24AWG gauge:

• Enables true balanced operation with 4.4mm termination
• Superior channel separation compared to shared ground designs
• Lower crosstalk between left and right channels
• Professional-grade wire gauge used in studio applications

Coaxial Shielding Technology

The ORCA incorporates multi-layer high-density shielding to protect the delicate audio signal from electromagnetic interference:

• Coaxial Design – Shield surrounds each conductor individually for maximum protection
• High-Density Coverage – Tight weave provides comprehensive shielding without adding excessive bulk
• EMI/RFI Rejection – Blocks interference from smartphones, Wi-Fi, and other electronic devices
• Preserved Signal Integrity – Clean signal path maintains tonal purity and detail
