Furutech FI-C15 NCF(R) Performance Slimline C15 IEC Connector

Furutech FI-C15 NCF(R) Is a High-End Slim IEC Connector Designed for Tight Spaces

Furutech FI-C15 NCF(R) is a high-performance slim body IEC connector engineered specifically for audiophiles facing clearance issues with recessed or obstructed IEC sockets. Whether you're working with a compact chassis design in high-end components like LINN streamers, Devialet amplifiers, or McIntosh systems, this precision connector solves spatial compatibility without sacrificing conductivity, shielding, or structural integrity.

Slim Profile Optimisation Ensures Effortless Compatibility

The Furutech FI-C15 NCF(R) IEC connector is purpose-built with a compact 22.0mm width and 30.0mm height, making it a seamless fit for equipment with restricted rear access. This slim profile design addresses a common issue in high-end audio equipment where tight IEC sockets limit aftermarket power cable upgrades. The FI-C15 allows precise integration with premium power cords, accommodating cable diameters from 6.6mm to 16.0mm and wire sizes up to 3.5mm² (12AWG).

A polycarbonate damping clamp with stainless steel screws ensures solid mechanical grip and resonance control, even with heavier audiophile-grade power cables.

Nano Crystal² Formula (NCF) Enhances Signal Integrity and Mechanical Damping

The FI-C15 NCF(R) uses Furutech’s proprietary Nano Crystal² Formula—a synergistic blend of nano-ceramic particles, carbon powder, and a crystalline matrix that possesses unique active properties. This composite material not only emits negative ions that neutralise static charge but also transforms thermal energy into far-infrared radiation, mitigating micro-vibrations and thermal distortion.

The internal structure and body of the connector incorporate this advanced NCF compound, delivering measurable damping performance that directly impacts sound clarity, imaging stability, and dynamic range.

Rhodium-Plated α (Alpha) Pure Copper Delivers High-Grade Conductivity

At the core of the Furutech FI-C15 NCF(R) is a rhodium-plated α (Alpha) pure copper conductor—selected for its exceptional conductivity, corrosion resistance, and long-term mechanical resilience. The α (Alpha) process, a signature Furutech technique, cryogenically treats and demagnetises the copper, ensuring signal purity and stability under demanding power loads.

The rhodium plating offers an added layer of durability and sonic precision, making this connector ideal for high-current applications and critical listening environments.

Purpose-Driven Construction for Audiophile-Grade Power Delivery

The body and inner cover of the FI-C15 NCF(R) are constructed from a reinforced nylon/fibreglass blend infused with Furutech’s anti-resonance NCF material. This creates a rigid yet damped housing that suppresses mechanical ringing and absorbs vibrational energy. By isolating and controlling internal and external resonance pathways, the connector maintains a low-noise power transmission path—vital for high-end systems where power purity translates into sonic fidelity.

The connector’s internal wiring is secured via set screw connection, supporting stable and consistent contact under thermal cycling and vibration, while also simplifying the termination process for custom cable builds.

Furutech FI-C15 NCF(R) Supports High-End System Optimisation

Furutech’s FI-C15 NCF(R) slim IEC connector isn’t just a space-saving component—it’s a precision-engineered upgrade for audiophiles seeking noise-free, dynamic-rich performance in power-critical environments. Its slim form factor, innovative NCF damping technology, and rhodium-plated α copper contact system make it indispensable for those optimising flagship systems where clean power delivery is non-negotiable.

Whether retrofitting high-end integrated amps or refining a system’s power interface, the FI-C15 NCF(R) sets a new benchmark for compact audiophile IEC connectors.
