FURUTECH FI-50 NCF (R)

The Furutech FI-50 NCF IEC connector represents one of the most advanced and refined solutions for power delivery in Hi-End audio systems. Designed without compromise, it is the result of Furutech’s in-depth engineering research and is conceived to ensure the highest purity in electrical signal transmission. The Alpha conductors in pure rhodium-plated copper provide superior conductivity and stability, while its 10A / 250V certification and compatibility with cables up to 20 mm in diameter make it suitable for even the most demanding applications.

The connector body features a multilayer structure of stainless steel and carbon fiber, combined with an acetal copolymer with damping and insulating properties. After extensive listening sessions, Furutech chose stainless steel and silver plating for the outer shell, blending mechanical solidity with aesthetic elegance. Inside, the exclusive NCF (Nano Crystal² Formula) material plays a key role: this unique compound, made from special crystals, nano-sized ceramic particles, and carbon powder, generates negative ions to eliminate static charges and converts thermal energy into low-frequency far-infrared. Its additional piezoelectric properties damp vibrations, minimizing unwanted noise and distortion.

Every construction detail is engineered to preserve signal purity and reduce any form of interference. Furutech’s patented Earth/Ground Jumper System eliminates electromagnetic disturbances induced in the connector’s fixing screws by channeling stray fields directly to ground. This meticulous attention to detail results in unmatched energy transfer optimization, maintaining a stable, linear, and interference-free electrical flow.

The result is a connector that not only ensures impeccable electrical performance but also actively enhances the listening experience, delivering a cleaner, more dynamic, and more detailed sound, in perfect harmony with Furutech’s Pure Transmission philosophy.
