RCA plugs, for example, should have robust construction and provide a tight and secure fit - at the very least. Add exceptional sound quality, ease of installation and a stunning finish that makes every cable project look professional, and you’ll wind up with a superior product that extracts every last bit of performance from your cable design. The new Furutech FT-111 Locking Collet RCA connectors meet - and surpass - those high standards of excellence. Furutech's engineers have examined every part of the signal and power path in order to optimize every single connection, and our extensive research has led them to the low metal mass FT-111. Furutech started with an Alpha pure copper one-piece conductor for designed for minimal impedance and then added the following features: Non-magnetic SUS set screw construction design Extremely insulated POM body with non-resonant SUS housing and non-magnetic stainless steel end ring One piece Rhodium conductors for the FT-111(R), or 24K gold-plated Alpha pure copper conductors injected with POM resin for the FT-111(G) Best of all, the FT-111 Locking Collet RCA connectors require no soldering. That means you’ll spend less time terminating and more time listening to the results. There legendary OEM parts are known all over the world for quality construction and superb sound, so discover for yourself how the Furutech FT-111 connectors can improve the performance of your cables.

Furutech have several complete lines of analog and digital, power and coaxial cables available in terminated and bulk quantities. Furutech make a wide range of highest quality OEM A/V connectors and other signal transfer parts including power, speaker, IEC and specialized Hyper Audio Quality outlet receptacles. All metal components are treated with Furutech’s proprietary 2-Stage Alpha Cryogenic and Ring Demagnetization Process during manufacture that ensures the lowest achievable levels of distortion and noise. Furutech offers a full line of elegantly engineered and designed power distribution and filter components made with an attention to detail found nowhere elsewhere. Furutech knows each and every part of the chain, no matter how small, is as important as the next, so they lavish maximum attention on all aspects of AC power transfer. As with cables, the separate parts go through the complete Alpha Process, and also benefit from the effects of GC-303, an applied material that absorbs EMI (Electromagnetic Interference). Furutech's Reference Line of cables and interconnects also include this anti-EMI technology. Furutech's multistep and highly specialized techniques result in extremely low-noise, fast and undistorted signal transfer that begins with the incoming AC mains power, an important factor overlooked by many. At Furutech, everyone there is passionately devoted to reaching the highest watermark in reference-grade A/V cables, OEM parts and accessories for home and car audio where Furutech maintain a very strong presence. Furutech's mission is building the absolutely best products imaginable whatever the effort involved, and offering them at a price/performance ratio that deeply satisfies every purchaser. Furutech’s Pure Transmission Design Concept improves every element of signal transmission, from the AC to the speaker.
