THE High End Performance AC Power Connector

Nonmagnetic Rhodium-Plated Conductors

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

The body of the connectors combines two “active” materials: Nano-sized ceramic particles and powdered carbon. (Only nano-sized ceramic particles effectively couples with carbon powder.) Nylon and fiberglass are incorporated as well forming an extremely effective, well damped, mechanically and electrically nonresonant connector body. That’s correct, they’re electrically damped as well.

Piezoelectric effects are the key. Furutech’s breakthrough in design and materials is based on employing nano-sized polycrystalline ferroelectric ceramic particles exhibiting electro-generative properties; mechanical pressure creates an electrical charge forming a bridge between electrical and mechanical oscillation.

Carbon powder exhibits thermal-conductive characteristics that interact with the charged ferro-ceramic particles converting their energy into heat that’s conducted away and released from the surface of the connector body!

These carefully chosen and tested “active” materials mechanically and electrically damp the connector and receptacle as they “interconvert” thermal, mechanical, and electrical energy for the finest Furutech Pure Transmission signal imaginable.

Press and Reviews

"If, like me, you appreciate taking many sonic steps forward and no steps backward, you’ll want to give these components a try."

Chris Martens, August 07 the Absolute Sound

“After many hours of listening, my appreciation for the Furutech References grew because of how non-fatiguing they can be while still revealing a very high level of detail. The extension of both treble and bass is excellent but it is the wholeness and balance of the sound that makes the Furutech Reference stand out."

Jay Fisher,

“If I had to limit myself to one key term whereby to paraphrase the essential Furutech quality, I'd opt for relaxed ultra resolution. … [Under high SPLs] there's no funny business of compression, smearing or skewing … The sense of big simply gets bigger and bigger and bigger. … There's something luxurious and silken about the Furutech connectors… routes and drapes easily."
