FI-50 NCF (R) Ultimate C15 IEC Connector Reduces Noise and Enhances AC Signal Integrity
FI-50 NCF (R) Ultimate C15 IEC connector (NCF head) stands at the forefront of Furutech’s Ultimate Power Connector Series, purpose-built for audiophiles and professionals demanding pristine AC delivery and minimal signal contamination. This high-performance connector reflects a synthesis of advanced materials science and precise engineering, designed to maintain signal purity across the most revealing audio systems.
FI-50 NCF (R) Connector Uses NCF Composite for Vibration and Static Control
FI-50 NCF (R) incorporates Furutech’s exclusive Nano Crystal² Formula (NCF) into its body and shell. This unique damping material blends crystalline particles, carbon powder, and nano-ceramics to suppress multiple forms of energy distortion. The formula actively generates negative ions to eliminate static, while converting heat into far-infrared energy—reducing thermal resonance that can blur fine detail in audio playback.
Combined with its piezoelectric properties, NCF works on both mechanical and electrical domains, enabling the connector to deliver ultra-stable, noise-free current with exceptional clarity and control.
FI-50 NCF (R) Plug Improves Signal Purity with Anti-Resonance Structure
The FI-50 NCF( R)’s multilayered shell is constructed from nonmagnetic stainless steel and silver-plated carbon fibre, integrated with an acetal copolymer that provides internal damping and insulation. This composite structure is the result of extensive listening tests and was selected for its ability to reduce high-frequency distortion and maintain tonal balance across the audio spectrum.
The result is a physically robust, resonance-controlled housing that preserves signal accuracy even in systems with sensitive analogue or high-resolution digital components.
FI-50 NCF (R) IEC Head Eliminates EMI Through Ground-Integrated Housing Design
The Earth/Ground Jumper System, a patented Furutech innovation, is embedded within the FI-50 NCF (R) to counteract magnetic interference. This system grounds the metal fixing screws, which are otherwise prone to carrying induced current and generating localised EMI. By channeling these stray currents to a dedicated internal ground point, the connector neutralises distortion at the structural level.
This ground-integrated design dramatically lowers the noise floor and improves dynamic range, helping preserve micro-detail and natural imaging—especially important in high-transparency, reference-grade systems.
FI-50 NCF (R) Conductors Feature Rhodium Plating for Long-Term Performance
The internal contacts of the FI-50 NCF (R) use α (Alpha) pure copper, treated cryogenically and demagnetised for superior conductivity. These conductors are rhodium-plated, ensuring a durable, corrosion-resistant interface that remains stable over time.
Rhodium’s hardness maintains consistent contact pressure, while its resistance to oxidation supports long-term signal consistency—a key advantage for system reliability in demanding environments.
FI-50 NCF (R) Connector Supports High-End Applications with Precision Fit
FI-50 NCF (R) Ultimate C15 connector is engineered for precision-fit cable integration, with a high-tension metal clamp that secures the conductor and minimises vibration-induced distortion. Its internal cavity supports a broad range of high-end AC cables, making it suitable for studio installations, audiophile power systems, and custom high-performance builds.
Each connector is hand-assembled, and natural variation in the silver-plated carbon fibre finish reflects the artisanal quality of production—without compromising performance or durability.
FI-50 NCF (R) Delivers Reference-Level Performance for Pure Transmission Power Chains
FI-50 NCF (R) functions as more than just a connector—it is a precision-engineered solution for maximising power delivery integrity. By eliminating electrostatic charge, grounding magnetic fields, and dampening vibration, it ensures that each component in the signal chain receives clean, uninterrupted current.
Whether used in DACs, preamps, monoblocks, or turntable power supplies, the FI-50 NCF (R) enhances the resolution, depth, and tonal accuracy of any high-end system, making it a cornerstone component in reference-level audio setups.
