Furutech FI-8.1(R) NCF High End Performance Slimline C7 IEC connector

Description

• A high-end C7 IEC connector, designed for audiophile-grade power cables where a standard IEC C13 plug won’t fit.

• NCF stands for Nano Crystal² Formula — Furutech’s proprietary material designed to absorb vibrations and static.

Key Features:

• Body Material: Nylon/fiberglass with NCF + Piezo Ceramic particles for damping.

• Contacts: Pure copper, plated with rhodium for conductivity and corrosion resistance.

• Design: Slimline profile — fits tight spaces where standard connectors are too bulky.

• Vibration Control: Multi-material hybrid damping (NCF + carbon powder + ceramic).

• Cable Fit: Accepts cables from 6.6mm to 15.0mm diameter.

• Wire Accommodation: 20 AWG to 16 AWG (0.5mm²–1.5mm²).

Performance Goals:

• Lower noise floor: By minimizing mechanical and electrical resonance.

• Better detail retrieval: By reducing microphonic distortions.

• Tighter bass, smoother highs: In line with typical Furutech tuning philosophy — refined but not overly “warm.”

Use Cases:

• Audiophile systems where equipment (like DACs, preamps, or high-end streamers) uses a C7 power input.

• Upgrading cheap molded C7 connectors for better system synergy.

Unlock the full potential of your audio and video components with the Furutech FI-8.1 NCF. Engineered for uncompromising performance, this slimline C7 connector features Furutech’s advanced NCF (Nano Crystal² Formula) technology to eliminate noise, suppress static, and deliver a stunningly clean, detailed signal. Pure copper rhodium-plated contacts ensure pristine power transfer, while the compact, vibration-damped body fits perfectly in space-limited setups.

Designed for those who refuse to settle for standard, the FI-8.1 NCF transforms everyday components into high-performance systems. Whether you’re upgrading a high-end DAC, streamer, or powered speaker, this connector makes every detail count.

Experience deeper bass, sweeter highs, and a lower noise floor — all from a simple, critical upgrade.

FEATURES

Nano Crystal² Formula (NCF)
Incorporated into selected Furutech products, NCF features a special crystalline material that has two ‘active’ properties. First, it generates negative ions that eliminate static. Second, it converts thermal energy into far infrared. Furutech combines this remarkable material with nano-sized ceramic particles and carbon powder for their additional ‘piezoelectric effect’ damping properties. The resulting Nano Crystal² Formula is the ultimate electrical and mechanical damping material. Created by Furutech, it is found exclusively in Furutech products.

Furutech is known the world over for a huge variety of top-quality OEM parts and delivers consistently superior results by following Pure Transmission principles; examine every link in the power and signal path and ultimately optimize each and every element.

New FI-8.1N series which delivers sonic improvements features a new design of cable clamp for firm grip and resonance control, and new slimline dimensions for use in tight spaces!
