FI-52 NCF(R) Furutech’s Ultimate Power AC Connector 20A (IEC)

“Rhodium plating on high purity copper conductors provides sophisticated high-resolution sound reproduction with a high SN. Low distortion, high precision sound depiction, high speed response. A high-performance connector with state-of-the-art rhodium plating.”
by Masamitsu Fukuda (Top Japanese Audio Commentator)

“All cabling, both power and audio, were by Furutech.
In my personal opinion, there is no other choice for cabling if you’re only happy with the absolute best.
Being very finicky about my sound, there’s only one cable manufacturer I fully trust.
…I have to say, after this test, I am astounded by the quality of this cable. You clearly hear there’s so much more space in the recording, such an openness I’ve never experienced before.”
by Brendon Heinst

“Furutech’s reputation in the audio connector sector is rock solid as it is for their apparently science-driven approach to even 　unconventional solutions like CD and LP demagnetizers … The [Piezo Powerflux AC cord] is possibly the most radical implementation of hi-tech materials anyone in this sector has attempted yet … Based on its noise killer damping action, I’d expect good results in systems which need greater organization, control and noise floor skills. Though far from cheap, Furutech’s construction, ingredients and fit ‘n’ finish are top shelf. That makes certain rather more expensive offerings look like crazy home-brew or unduly funky efforts.”

NCF Piezo Ceramic Series Connectors •
A Furutech First!
Furutech’s Pure Transmission FI-50 NCF Piezo Ceramic series connector bodies and housings feature several breakthrough construction techniques.
A multilayer nonmagnetic stainless steel and silver plated carbon fiber shell incorporates a special damping and insulating acetal copolymer. Furutech settled on stainless and silver plated carbon fiber for the outer housing after extensive listening sessions with Japanese industry figures and audiophiles.

The body of the connectors incorporates an “active” damping material: Nano Crystal² Formula – Nano Crystalline, Ceramic and Carbon Powder
Incorporated into select Furutech products, Nano Crystal² Formula — NCF is comprised of a special crystalline material that has two “active” properties. First, it generates negative ions that eliminate static and secondly, it converts thermal energy into far-infrared. Furutech then combines this remarkable crystalline material with nano-sized ceramic particles and carbon powder for their additional “Piezo Effect” damping properties. The resulting Nano Crystal² Formula is the ultimate electrical and mechanical damping material – only found in Furutech products!
Nano Crystal² Formula eliminates static, “interconverts” thermal, mechanical and electrical energy and damps vibrations—all for the finest Furutech Pure Transmission signal imaginable.

Furutech Pure Transmission Philosophy •
Meticulous build quality is a large part of the engineering equation. Furutech Pure Transmission technology turns a macro lens on every element of power and signal transfer applying optimized engineering solutions to well-known problems such as contact resistance, EMI and RFI rejection, grounding, and using the best materials and processes available.

Floating Magnetic Field Effects •
The Floating Field Damper completely solves the biggest problem you never realized you had by star grounding the metal parts in which floating magnetic fields are created by current flow through the connector. A precisely engineered, sprung metal bridge ties the various parts together and shunts the potential to ground, significantly reducing distortion for ultra clean and stable power transfer.
Current flowing through the power connector creates a magnetic field, just as an insulated conductor creates both electromagnetic and electrostatic fields. Furutech engineers found this magnetic field induces current flow (and a small magnetic field) in the screws holding the connector together! These magnetic fields interfere with the larger magnetic field around the conductor and connector.
Furutech’s total attention to detail and elegant engineering neatly solves the problem. The Floating Field Damper connects the securing screws to a ground terminal within the plug completely eliminating the field disturbances they cause. The stray fields are grounded by a series of interlocking parts within the connector that attach to the ground conductor. The Jumper System is available in Furutech NEMA Power and IEC Connectors.　The Earth/Ground Jumper System Carries US Patent No. 6,669,491
