Furutech FI-28 High Performance C15 IEC Connector (each)

Furutech FI-28 Powers High-End Systems with Pure Transmission Engineering

Furutech FI-28 High End Performance IEC Connector is a premium power interface designed to deliver clean, stable AC current to high-fidelity audio components and critical AV gear. It embodies Furutech’s Pure Transmission engineering ethos, which addresses power transfer at both the macro and micro levels by mitigating common system degradations like contact resistance, EMI, RFI, and mechanical resonance. Crafted for audiophiles and engineers seeking exacting build quality and noise-free performance, the FI-28 offers uncompromised signal clarity from source to circuit.

Furutech FI-28 Maximises Conductivity with α (Alpha) Treated Copper

Furutech FI-28 IEC connectors are engineered around α (Alpha) pure-copper conductors, which undergo a proprietary cryogenic and demagnetisation process to enhance electron flow and structural stability. This optimised metallurgy improves contact conductivity while minimising the signal smear often caused by thermally induced molecular misalignment. The FI-28(G) model features 24k gold-plated contacts, preferred for warmth and smooth tonal characteristics, while the FI-28(R) employs rhodium plating, offering a tighter, more revealing sonic presentation—ideal for reference-grade systems requiring absolute detail retrieval.

Furutech FI-28 Reduces Distortion with Floating Field Damper System

Furutech’s patented Floating Field Damper System, embedded in the FI-28(R), neutralises the internal magnetic fields generated by current flow within the connector housing. These fields can distort signal flow and introduce low-level noise. The damper acts as a grounding bridge that ties all metal parts together, effectively shunting magnetic potential to ground and preserving current integrity. The FI-28(G) complements this with Furutech’s Earth Jumper System, a parallel innovation that maintains equipotential grounding across all conductive surfaces—lowering distortion and enhancing dynamic control in complex systems.

Furutech FI-28 Suppresses Resonance Using Carbon-Infused Composite Housing

Furutech FI-28 IEC power connectors are housed in a nylon/fibreglass composite shell embedded with carbon particles that suppress vibrational energy and absorb structural resonance. This feature is especially critical in high-current environments, where micro-vibrations can influence internal contact pressure and increase electrical noise. By damping mechanical interference at the housing level, the FI-28 ensures a tighter connection interface, prolongs the life of the contact points, and delivers greater tonal consistency across power-demanding setups.

Furutech FI-28 Offers Broad Compatibility with Audiophile Power Cables

Furutech FI-28 power connectors support a wide range of cable sizes—from 6.0mm to 17.5mm in diameter—making them suitable for use with bulky, heavily shielded audiophile power cords as well as leaner, high-efficiency designs. The precision-machined metal cable clamp reinforces mechanical stability and reduces distortion caused by cable movement or connector flex, ensuring long-term reliability in both stationary and mobile applications. The FI-28 fits seamlessly into crowded racks or compact installations with its space-conscious 76.2mm body length, while preserving robust build quality and visual elegance.

Furutech FI-28 Reflects Uncompromising Japanese Craftsmanship

Furutech’s FI-28 Series IEC connectors stand at the intersection of scientific innovation and artisanal precision. Designed and manufactured in Japan, every connector is the result of rigorous materials testing and performance-driven engineering. These connectors pair perfectly with Furutech’s own high-end cables, such as the Piezo Powerflux, or with other elite-grade AC cables where system noise suppression, current linearity, and thermal stability are mission-critical. For system designers and audiophiles building noise-free, dynamically expressive systems, Furutech FI-28 offers a professional-grade solution that leaves no variable unrefined.
