Furutech FT-763SM(R) 6.3mm Stereo Connector (each)

Furutech FT-763SM(R) Connector Delivers Audiophile-Level Signal Integrity

Furutech FT-763SM(R) 6.3mm stereo connector is a high-performance TRS audio plug engineered for audiophiles, sound engineers, and cable artisans seeking precise signal transmission with minimal resistance and long-term durability. Built from premium materials and crafted to exacting standards, this connector exemplifies Furutech’s commitment to sonic purity and mechanical excellence.

FT-763SM(R) Uses Rhodium-Plated Alpha Copper for Maximum Signal Purity

FT-763SM(R) stereo connector features a one-piece central conductor made from Furutech’s α (Alpha) pure copper, selected for its high conductivity and cryogenically treated to reduce internal stress. Rhodium plating enhances corrosion resistance and ensures consistent electrical contact over time, even under demanding conditions.

The internal signal path is uninterrupted by joints or seams, reducing micro-resistance and phase distortion. The ground contact, also crafted from rhodium-plated α (Alpha) hybrid copper, provides stable grounding and suppresses low-frequency interference — crucial for balanced audio systems and precision monitoring setups.

Specialised Nylon Glass Fibre Insulation Preserves Signal Integrity

Furutech FT-763SM(R) connector employs a high-grade nylon glass fibre resin as its insulator, chosen for its low dielectric constant and resistance to deformation under heat. This material maintains stable capacitance values across frequency ranges, preserving phase coherence and transient accuracy.

Its electrical insulation is further complemented by vibration-damping properties, which help reduce mechanical noise transmission through the plug body — an often-overlooked source of sonic degradation in high-resolution systems.

Stainless Steel Shell and Copper Alloy Clamp Deliver Rugged, Resonant-Free Design

FT-763SM(R) audio plug is housed in a stainless steel enclosure that effectively dampens resonance while providing robust mechanical protection. The density and rigidity of the shell reduce ringing and microphonic artefacts, making this connector ideal for high-end audio cables and custom terminations where sonic neutrality is essential.

The internal cable clamp, made from copper alloy, provides strong mechanical anchoring for cables with core insulation diameters up to 8.0mm. This clamp prevents stress on solder joints, ensuring long-term reliability in both stationary and mobile audio systems.

FT-763SM(R) Accommodates Premium Cable Builds and Professional Applications

Furutech FT-763SM(R) 6.3mm plug supports soldered connections for maximum signal fidelity and is designed for use with a wide range of cable assemblies, including high-end instrument cables, studio patch cords, and reference-grade headphone terminations. Its engineering makes it especially well-suited for custom cable builders demanding superior material quality and precise construction.
