LUNA CABLES GRIS Series Neo Vintage Copper Conductor USB Cable

Product Concept

USB cables are one of the main channels in modern digital audio that connect PC audio and network players to DACs. However, typical USB cables have a fundamental problem because the power and signal lines run within the same cable, making power noise easily interfere with the signal.

Luna Cables GRIS USB addresses this challenge by combining four LCNV 26AWG conductors with cottondielectriccombined with a structure that protects the signal with a double tin-plated copper shield. By sandwiching the supplementary cotton insulation layer between two shielding layers, it blocks both the intrusion of external noise and the leakage of internal noise in two stages.

Luna Cables: Cables from Montreal, Born from Artisans

Luna Cables is a handmade audio cable brand based in Montreal, Quebec, Canada. All products are produced in small batches in the workshop, with each strand finished by artisans. The attention to detail and attention to materials that mass-produced products lack, support Luna Cables' musicality.

■ LCNV Conductor (Luna Cable Neo Vintage): A one-of-a-kind conductor created by vintage processing machines

LCNV is Luna Cable's proprietary copper conductor produced using its own formulation and manufacturing method. By deliberately using vintage wire processing machines instead of cutting-edge CNC machines, we produce conductors with unique crystal structures and flexibility that modern precision machinery cannot replicate. This approach of "bringing the goodness of the old" to modern hi-fi is the core of Luna's sound.

■ Waxed Cottondielectric: Vibration control and musicality provided by natural materials

LCNV also features waxed cottondielectricIt is covered as such.dielectricis a term that refers to the electrical properties of the coating material that covers a conductor; the lower the dielectric constant of the material, the less unnecessary interference with the signal waveform. Wax-impregnated cotton has a lower dielectric constant than plastic-based materials, minimizing signal interference while providing high vibration damping. It absorbs minute noises caused by external vibrations, creating a smooth and rich musical expression that does not feel oppressive while increasing the focus of the sound.

■ Uncompromising craftsmanship, with all contacts finished by hand soldering

All connections on all Luna Cables cables are hand soldered. The precise contact quality that cannot be obtained through mass production using machines is directly linked to signal transparency and long-term reliability. This painstaking process is one of the reasons why Luna Cables is on par with top audio brands.

■ Cotton jacket: Made of natural materials from inside to outside

The exterior is made of a cotton jacket that is flexible and easy to handle. It has appropriate flexibility and sound absorption properties not found in synthetic resin tubes, and suppresses unnecessary tension and vibration propagation during installation. Luna's philosophy of using natural materials from inside to outside is evident here.

Main features

• LCNV 26AWG conductor x 4 (cotton)dielectric）：The USB standard power lines (VBUS/GND) and signal lines (D+/D-) are each constructed with LCNV 26AWG conductors. Cotton on each conductordielectricis coated to minimize line-to-line interference.
• Supplementary cotton insulation/damping layer:There is a supplementary cotton layer on the outside of the first layer shield. By sandwiching cotton between the shields, it simultaneously provides physical vibration damping and electrical insulation, creating a structure in which the two shield layers do not interfere with each other.
• Double tinned copper mesh shield:Adopts a double-layered blade shield with a supplementary cotton layer in between. It has a two-stage protection structure, with the first layer preventing leakage of internal noise and the second layer blocking the intrusion of external noise. Effectively eliminates high frequency noise and interference from power lines that are easily carried by USB cables.
• Cotton jacket:The flexible and easy-to-handle cotton exterior reduces the load during installation. Absorbs unnecessary tension that tends to occur when connecting to a PC or DAC.
• Gold plated USB connector, all contacts hand soldered:The contacts are gold plated to prevent contact deterioration due to oxidation over time. You can specify two combinations when ordering: USB-A (input) → USB-B (output) or USB-A (input) → USB-C (output). All contacts are hand soldered by craftsmen.

The USB cable that connects the PC audio/network player/DDC (digital-to-digital converter) and DAC is a path where the quality of the noise control is directly linked to the sound quality. GRIS USB keeps this path as clean as possible thanks to Luna's material philosophy and double shield construction.
