The Oyaide ACROSS 750 V2 is a coaxial interconnect cable designed to ensure stable analogue transmission with low parasitic capacitance. It relies on a 102SSC copper centre conductor combined with a proprietary C.I.S. (Cross-Insulated-Stabilizer) structure incorporating an air layer, in order to reduce dielectric interactions and preserve signal integrity, particularly in the high-frequency range.
Intended for high-fidelity audio links, it combines a controlled-geometry coaxial architecture with low-dielectric-constant polyolefin insulation, limiting losses and internal interference while maintaining high mechanical stability. This approach allows it to integrate into demanding systems where control of capacitance, internal vibrations and conductor/insulation interactions directly conditions the accuracy of reproduction.
The ACROSS 750 V2 relies on the proprietary 102SSC conductor, drawn from primary copper conforming to JIS C1011 to eliminate any impurities associated with recycling, while a surface stripping process removes residual contaminants to promote uniform conduction. This approach is extended through drawing via natural diamond dies, refining the strand structure and improving their consistency, while maintaining a manufacturing tolerance of ±1µm that limits electrical variation. The whole, completed by a double annealing process reducing internal mechanical stress, achieves a conductivity of 102.3% IACS, ensuring stable and predictable signal transmission.

The patented 3E technology is based on the concentric combination of three distinct strand diameters, allowing the internal arrangement to be densified while reducing the gaps between conductors. This geometric organisation improves bundle cohesion and ensures a perfectly circular cross-section after twisting, promoting uniform contact with the insulation and limiting thickness irregularities. Beyond the mechanical precision, this homogeneous structure translates into more consistent electrical characteristics, contributing to greater signal stability across the full bandwidth.
The cable adopts a C.I.S. (Cross-Insulated-Stabilizer) structure that introduces a cross insulation incorporating an air layer acting as a damper, reducing parasitic capacitance while improving high-frequency response. This approach differs from conventional solutions in that no massive damping materials are used — vibration dissipation is instead ensured by the geometry of the trapped air itself, limiting internal mechanical interactions that could degrade the signal.
This architecture extends into a coaxial configuration where the centre conductor is supported at discrete points rather than along its full surface, reducing interactions with the outer shield while maintaining high mechanical stability. The use of a polyolefin with a low dielectric constant — approximately four times lower than PVC — maintains effective insulation while limiting energy storage, resulting in faster signal recovery and improved resolution of micro-details in high-fidelity configurations.

The assembly is enclosed in a halogen-free polyethylene outer jacket, selected for its stable dielectric properties and low interaction with the signal, while contributing to the mechanical protection of the cable in both domestic and professional environments. This outer sheath maintains consistent electrical performance by limiting external influences, while its composition ensures controlled dissipation of thermal and mechanical stress.
