Piezo Ceramic Series Connectors • A Furutech First!

Furutech’s Pure Transmission FI-50R 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. 

• α (Alpha) Pure Copper Rhodium plated conductor 
• Earth (Ground) Jumper System (US Patent No.: 6,669,491 )
• Nylon/fiberglass body incorporating nano sized ceramic particles for absorption of vibration resonance.
• Multi layered nonmagnetic stainless steel and carbon fiber housing and incorporating acetal copolymer. The best of damping and insulation materials for improvements in frequency extension and tonal quality..
• Specified for cable diameters from 6mm to 20mm
• Dimensions: Body length 44mm x 40.5mm diameter x 80.3mm overall length
• Metal cable clamp for improved grip and reduction of mechanically and electrically induced distortion.

The Furutech FI-50R is considered the best IEC connector on the market by many leading audiophiles, buy now and be amazed at the difference it makes to any system.

  1. Rated 5 out of 5

    If you have high end gear then this plug can do no wrong. Amazing quality and feel to it, you are safe in the knowledge that your sources are getting the purest electricity from the best possible connection. It’s expensive yes but worth it.

  2. Rated 5 out of 5


    As soon as you pick this IEC up you can feel that it is a quality product. The difference it makes is almost unbelievable, greater detail and depth all round . Needs a few weeks runnning in before the full effect kicks in.
