LUNA CABLES GRIS Series Neo Vintage Copper Conductor USB Cable

Product Concept

USB cables are one of the main pathways in modern digital audio for connecting PCs, audio systems, and network players to DACs. However, typical USB cables fundamentally face the problem that, due to their structure where the power line and signal line run within the same cable, power noise easily interferes with the signal.

For this issue, the Luna Cables GRIS USB uses four LCNV 26AWG conductors with cottondielectricIt combines these elements and responds with a structure that protects the signal with a double tin-plated copper shield. By sandwiching a supplemental cotton insulation layer between the two shield layers, it blocks external noise intrusion and internal noise leakage in two stages.

Luna Cables: Cables Born from the Hands of Artisans in Montreal

Luna Cables is a handmade audio cable brand based in Montreal, Quebec, Canada. All products are produced in small quantities in a workshop, with each cable finished by the hands of artisans. The care not found in mass-produced items and the focus on materials support the musicality of Luna Cables.

■ LCNV Conductors (Luna Cable Neo Vintage): Unique Conductors Created by Vintage Processing Machines

LCNV is an in-house manufactured copper conductor produced using Luna Cable’s own unique blend and proprietary methods. Instead of using cutting-edge CNC machines, vintage wire processing machines are deliberately employed, resulting in conductors with a unique crystal structure and flexibility that modern precision machinery cannot replicate. This approach of applying the virtues of 'old things' to modern hi-fi is at the core of the Luna sound.

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

LCNV also has waxed cottondielectricIt is coated as.dielectricThis refers to the electrical characteristics of the insulating material that covers the conductor. The lower the dielectric constant of the material, the less unwanted interference occurs in the signal waveform. Cotton impregnated with wax has a lower dielectric constant compared to plastic-based materials, minimizing interference with the signal while also providing high vibration damping effects. It absorbs fine noise caused by external vibrations, enhancing the focus of sound while delivering smooth and rich musical expression without a sense of pressure.

■ All connections hand soldered, uncompromising craftsmanship

All Luna Cables are hand-soldered at each connection point (All connections hand soldered). The precise contact quality, which cannot be achieved by mass production machines, directly contributes to signal transparency and long-term reliability. This painstaking process is one of the reasons why Luna Cables can stand shoulder to shoulder with top-tier audio brands.

■ Cotton Jacket: Unified natural material from inside to outside

The exterior uses a flexible and easily manageable cotton jacket. It has moderate flexibility and sound absorption not found in synthetic resin tubes, suppressing unnecessary tension and vibration transmission during installation. Luna’s philosophy of thoroughly unifying materials with natural substances from inside to outside is also reflected here.

Main Features

• LCNV 26AWG conductors × 4 (cottondielectric）：The USB standard power lines (VBUS and GND) and signal lines (D+ and D-) are each composed of LCNV 26AWG conductors. Each conductor has cottondielectricIt is coated, minimizing inter-line interference.
• Supplementary Cotton Insulation and Vibration Damping Layer:A supplementary cotton layer is provided on the outside of the first shield. By inserting 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 Tin-Plated Copper Mesh Shield:Adopts a double-layer braided shield with an intervening supplementary cotton layer. The first layer prevents leakage of internal noise, while the second layer blocks the intrusion of external noise, providing a two-step protection structure. It effectively eliminates high-frequency noise that tends to affect USB cables and interference from power lines.
• Cotton Jacket:The flexible and easy-to-handle cotton exterior reduces stress during setup. It absorbs excessive tension that can occur when connecting to PCs or DACs.
• Gold-plated USB connectors & all-hand soldered contacts:Gold plating is used on the contacts to prevent connection deterioration due to oxidation over time. You can specify the combination at the time of order: USB-A (input) → USB-B (output) or USB-A (input) → USB-C (output). All contacts are hand-soldered by craftsmen.

The USB cable connecting a PC audio system, network player, or DDC (digital-to-digital converter) to a DAC is a path where noise countermeasures directly affect sound quality. The GRIS USB, following Luna's material philosophy and with its double-shielded structure, keeps this path as clean as possible.
