What customers say
Enthusiasts highly regard the Furutech FT-903 RCA Jacks for their superior build quality and sonic performance. Users consistently highlight the robust construction using premium materials, suggesting excellent durability and signal purity. The core appeal is the tangible audio improvement; listeners report enhanced clarity and better soundstage definition after installation. While these components command a premium price, the consensus among builders is that the resulting fidelity gains justify the investment. These jacks are viewed as a benchmark for custom amplifier and preamp projects where uncompromising signal integrity is the main goal, leading to deep user satisfaction.
Know before you buy
Rhodium plating is generally favored for its extreme durability and a slightly more analytical, detailed sound profile. 24k Gold plating offers a warmer, smoother sonic signature and is highly resistant to oxidation, making it a classic choice for long-term reliability.
The FT-903 is designed for standard chassis mounting. Given the overall length of 40mm, ensure your chassis panel has enough clearance behind it to accommodate the jack and your internal wiring.
These jacks accommodate a maximum wire diameter of 4.5mm. This provides enough flexibility for most high-quality audio signal cables used in internal component wiring.
Installation requires standard soldering equipment to create a permanent connection to the conductor. Because the body is constructed from high-temperature resistant Liquid Crystal Polymer, it is less prone to melting during the soldering process than standard plastic connectors.
The FT-903 features color-coded nylon center insulation in red and white. This allows for quick, error-free identification of your left and right signal paths during the build process.
