Furutech FI-C15(G) High Performance C13 IEC connector

Description

The Furutech FI-C15(G) is a high-quality IEC C15 power connector designed for audiophile-grade power cables and high-performance audio systems. Manufactured in Japan by Furutech, the FI-C15(G) combines advanced materials, precision engineering, and gold-plated conductors to deliver exceptional electrical conductivity, mechanical stability, and long-term reliability.

Developed for demanding audio and AV applications, the Furutech FI-C15(G) is ideal for use with amplifiers, power conditioners, source components, and other equipment requiring a high-current IEC C15 connection. It is specifically engineered to reduce contact resistance, minimize electrical noise, and improve overall power delivery—critical factors in high-end audio performance.

Designed for High-End Power Cable Upgrades

The Furutech FI-C15(G) is part of Furutech’s well-known FI-Series connectors, widely respected among audiophiles and cable manufacturers worldwide. Whether you are building a custom power cable or upgrading an existing one, this gold-plated IEC connector ensures stable, low-impedance power transfer from your AC cable to your component.

Power quality directly affects sound quality. Poor contact pressure, low-grade materials, or oxidation at the IEC interface can introduce resistance, micro-arcing, and electrical noise. The FI-C15(G) addresses these issues with premium construction and precision machining.

High-Conductivity Gold-Plated Contacts

The “(G)” designation indicates 24k gold-plated α (Alpha) pure copper conductors. Furutech’s Alpha process includes cryogenic treatment and demagnetization, improving molecular structure and enhancing conductivity.

Gold plating provides:

• Excellent corrosion resistance

• Stable long-term conductivity

• Smooth and natural tonal balance

Compared to rhodium-plated versions, the gold-plated FI-C15(G) is often preferred for systems seeking:

• Slightly warmer tonal character

• Natural midrange presentation

• Smooth high-frequency performance

High-Quality Nylon/Fiberglass Body Construction

The FI-C15(G) features a nylon/fiberglass housing, engineered for durability and vibration resistance. This material combination offers:

• High mechanical strength

• Heat resistance

• Electrical insulation stability

The internal clamping system ensures secure cable fixation, reducing micro-vibrations that could affect signal stability and contact pressure.

Optimized for High-Current Applications

The IEC C15 design allows the connector to be used with components that generate higher heat, such as:

• Power amplifiers

• Integrated amplifiers

• Power conditioners

• High-performance source components

The FI-C15(G) supports secure termination of large-gauge power cables, making it suitable for serious audiophile power cable builds.

Audible Performance Benefits

When used in high-quality power cables, the Furutech FI-C15(G) can contribute to:

Improved Power Delivery

• Lower contact resistance

• More stable current flow

• Reduced electrical stress on components

Lower Noise Floor

• Cleaner background

• Reduced AC-related interference

Enhanced Tonal Balance

• Smooth, natural midrange

• Refined high frequencies

• Controlled, articulate bass

Improved Dynamics and Clarity

• Better transient response

• More effortless musical presentation

• Enhanced micro-detail retrieval

As with all high-quality power connectors, the performance improvement depends on system resolution and cable design, but in well-optimized systems, the FI-C15(G) offers a clearly audible upgrade over standard molded IEC connectors.

Ideal Applications

The Furutech FI-C15(G) is ideal for:

• Custom audiophile power cable builds

• Upgrading factory-installed IEC connectors

• High-end hi-fi systems

• Home theater power systems

• Professional audio setups

It pairs exceptionally well with premium AC cables and high-quality wall plugs such as other Furutech connectors.
