Furutech FT-903(R) / (G) High End Performance RCA Socket (set of 2)

Furutech FT-903(R)/(G) Delivers High-End RCA Socket Performance

Furutech FT-903(R)/(G) RCA sockets are high-end audio connectors engineered to deliver uncompromising signal integrity for audiophile-grade systems and premium custom installations. These RCA terminals reflect Furutech’s philosophy of precision engineering and sonic transparency, making them an ideal solution for both OEM applications and DIY projects that demand flawless signal transfer.

Furutech FT-903(R)/(G) Features a Pure Copper Signal Path

Furutech FT-903 RCA sockets use an α (Alpha) pure copper conductor at the core of their design. This oxygen-free, cryogenically treated conductor ensures ultra-low impedance and delivers precise, uncoloured signal transmission across the audio spectrum. Available in either 24k gold-plated FT-903(G) or rhodium-plated FT-903(R) variations, both finishes provide superior contact resistance and corrosion protection, enhancing long-term performance in demanding environments.

Furutech FT-903(R)/(G) Uses Liquid Crystal Polymer for Resonance Control

Furutech FT-903 RCA connectors integrate a liquid crystal polymer (LCP) resin body that acts as both a high-durability insulator and an advanced vibration-damping medium. This specialised compound significantly reduces micro-resonances that would otherwise introduce distortion, maintaining signal purity throughout the chain. The same LCP material is employed in the chassis nut, strategically suppressing unwanted mechanical vibrations right at the mounting point — a rare detail that elevates the FT-903 above conventional RCA terminals.

Furutech FT-903(R)/(G) Combines Audiophile Engineering with Secure Fit

FT-903(R)/(G) RCA sockets are designed to accommodate core diameters up to 4.5mm, with a robust 16.0φ x 40.0 mm form factor that provides solid mechanical stability for chassis mounting. The plated, lead-free copper alloy chassis nut ensures firm engagement with enclosures while maintaining clean electrical contact. Solder terminals are precision-engineered for consistent, reliable connections, allowing integrators and enthusiasts to achieve optimal system performance with confidence.

Furutech FT-903(R)/(G) Enhances Sound with Custom-Tuned Materials

The FT-903 RCA connectors are built from carefully selected, sonically neutral materials, including a nylon resin colour ring and central insulation layer that visually indicates channel polarity while maintaining non-conductive integrity. The result is a physically and electrically optimised design that aligns with Furutech’s proprietary resonance control and grounding strategies — innovations rooted in extensive R&D and empirical listening tests.

Furutech FT-903(R)/(G) Offers Exclusive Construction in a Patent-Pending Design

This Furutech RCA terminal features a unique, patent-pending construction exclusive to the brand. Every mechanical and electrical aspect of the FT-903 is tuned to deliver high-resolution, low-noise signal transfer for elite audio systems. Whether implemented in reference-grade amplifiers, custom-built DACs, or high-fidelity preamps, the FT-903(R)/(G) delivers transparent performance that exposes detail, nuance, and dynamic range often lost through standard connectors.
