FURUTECH FI-15 Plus High-Performance Rhodium IEC Connector - Single

In this review the FURUTECH FI-15 Plus is examined as a single high-performance IEC connector intended for serious audio and AV enthusiasts who want to improve power delivery at the component level. The bottom line: this is a precision replacement IEC connector built around a rhodium-plated pure-copper conductor and resonance control features, and it most benefits systems where small improvements in noise, mechanical stability and contact quality translate to audible gains. The review focuses on build, installation considerations and who stands to gain from swapping stock connectors for this Furutech unit.

Key Features

• Rhodium-plated pure copper conductor: Provides a low-resistance, corrosion-resistant contact surface intended to preserve signal purity and long-term contact reliability.
• Floating Field Damper System: Reduces induced magnetic fields near the connector to limit subtle noise and improve background quietness in sensitive audio chains.
• New plating technique and finish: The updated plating and durable surface aim to deliver sonic improvements while resisting wear from repeated insertions.
• Polycarbonate cable damping clamp: The clamp with stainless screws secures cables from 6.6mm to 15.0mm and helps control resonance and microphonics at the termination point.
• Nylon/fiberglass body and inner cover: A rigid housing that combines electrical insulation and mechanical stability for consistent connection geometry.
• Compact dimensions and set screw connection: Small footprint (35.0mm x 34.0mm x 72.5mm) and a set screw connection make it a practical OEM-style replacement in many power cords and equipment panels.

Who It's For

This connector is aimed at audiophiles, custom cable builders and professional installers who prioritize component-level improvements and prefer high-quality OEM parts. Those running sensitive home audio systems, two-channel stereo rigs or studio equipment that responds to power-delivery refinements will find the FI-15 Plus most rewarding.

It is not intended for casual users who want a simple inexpensive replacement; buyers should be comfortable with termination work or have access to a technician. If you need a multi-connector kit or cheap mass-market replacements, a different, lower-cost option will serve better.

Pros & Cons

Pros

• Exceptional contact metallurgy with rhodium-plated pure copper to maintain low resistance and corrosion resistance.
• Built-in Floating Field Damper System helps reduce magnetic interference and contribute to a quieter background.
• New cable clamp and durable plating improve mechanical grip and long-term reliability in installations.
• Compact form factor and clear specification for cable diameters make it flexible for many custom cables.

Cons

• Sold as a single connector so bulk projects may require multiple purchases and professional assembly for best results.
• Requires basic termination skills or a technician; not plug-and-play for users unfamiliar with set-screw connections.

Our Verdict

The FURUTECH FI-15 Plus is a focused upgrade for anyone assembling high-end power cords or replacing worn OEM IECs in critical audio gear; its rhodium-plated pure-copper contact, field damper and improved clamp deliver measurable mechanical and electrical refinement. It represents good value when improved noise floor and connection stability matter, provided the buyer accepts that it is sold individually and requires proper termination.

Frequently Asked Questions

Is this sold as a single connector?
Yes, the FI-15 Plus is sold as a single connector so order the quantity you need for multi-cable projects.

What cable sizes will it accept?
It is specified for cable diameters from 6.6mm to 15.0mm and supports wire sizes up to 5.5mm2 (10AWG) maximum.

Does it require special tools to install?
Installation uses set screws and stainless screws for the clamp; basic hand tools and soldering or proper conductor preparation are recommended for a secure termination.
