Furutech FI-11-N1 Performance C15 IEC Connector (each)

Furutech FI-11-N1 Delivers High-Performance IEC Connection

Furutech FI-11-N1 High Performance IEC Connector is a premium-grade power connector engineered to elevate the integrity of audio system performance. Designed according to Furutech’s renowned Pure Transmission philosophy, this IEC connector is precision-manufactured to reduce signal loss, control resonance, and deliver enhanced electrical conductivity for demanding audiophile and professional applications.

FI-11-N1 Improves Power Transfer with Premium Materials

Furutech FI-11-N1 IEC connectors use α (Alpha) processed phosphor bronze conductors to ensure low resistance and minimal signal degradation. This material undergoes a proprietary cryogenic and demagnetisation treatment, enhancing electrical flow by stabilising the conductor’s molecular structure. The result is an exceptional signal-to-noise ratio, critical for revealing micro-dynamic details and preserving sonic purity in high-end systems.

The connector housing is crafted from durable nylon/fibreglass for the front body, while the outer shell is precision-moulded polycarbonate. These materials offer both mechanical strength and internal damping, effectively isolating the connector from external vibrational interference. A black nonmagnetic stainless steel clamp secures the cable firmly, controlling resonance and supporting overall signal stability under load.

FI-11-N1 Enhances Sonic Clarity Through Advanced Plating

Furutech’s FI-11-N1 Series distinguishes itself with advanced electroplating options that tailor the sound profile to listener preferences. The Rhodium-plated version delivers high resolution and superior transparency. Ideal for systems needing enhanced treble articulation and wide dynamic contrasts, the Rhodium finish excels in high-frequency detail retrieval. The Japanese audio commentator Masamitsu Fukuda notes its ability to produce a “super responsive, delicate, expressive and neutral sound,” revealing sonic subtleties across the frequency spectrum.

In contrast, the Gold-plated variant is suited to those who value warmth and musicality. The thicker-than-previous gold plating introduces a smoother tonal balance and an enriched harmonic character. Enhanced low-frequency extension and a stable soundstage make this version particularly attractive for tube-based or warmer-sounding systems.

Both finishes are applied using Furutech’s newly developed plating process, which increases durability while improving conductivity. This results in consistent long-term performance and a highly reliable electrical contact.

FI-11-N1 Offers Versatility with Secure Fit and Broad Compatibility

Furutech FI-11-N1 connectors are designed to accommodate a wide range of power cable diameters, from 6.6mm to 16.0mm, and up to 20mm when using a longer screw. The internal construction supports firm strain relief through a precision stainless steel clamp, maintaining a secure electrical connection and suppressing unwanted mechanical vibration.

Engineered with a 2-pole + earth configuration, the connector is rated for both 10A/250V and 15A/125V AC systems. This makes it suitable for use with a diverse array of audio equipment, including integrated amplifiers, power conditioners, digital source components, and active loudspeakers.

A Floating Field Damper System is integrated into the FI-11-N1 design, mitigating the influence of induced magnetic fields that often develop around AC connections. This advanced mechanism works to suppress EMI (electromagnetic interference), ensuring consistent and interference-free power delivery to sensitive audio components.

FI-11-N1 Integrates Seamlessly into High-End Audio Systems

Furutech FI-11-N1 High Performance IEC Connector is available in both Gold-plated and Rhodium-plated versions, each tailored for distinct sonic preferences. The Gold-plated FI-11-N1 offers a warm, smooth, and harmonically rich sound, ideal for systems where musicality and tonal fluidity are desired. The Rhodium-plated FI-11-N1 delivers exceptional clarity, high-frequency precision, and a neutral tonal balance, making it perfect for revealing detail and dynamic contrast in high-resolution audio setups. Both versions feature α (Alpha) phosphor bronze conductors, robust polycarbonate shells, and a stainless steel cable clamp for secure, vibration-controlled connections.
