NCF Clear Line-LAN Line Optimizer
Designed for easy plug-and-play use, this advanced LAN optimizer significantly enhances signal-to-noise (S/N) ratio, delivering exceptional clarity and detail. Without altering the original sound, it brings out the nuances of your audio source for a more immersive experience. Featuring 24k gold-plated, nonmagnetic LAN connectors and a specially engineered EMI shield, this device ensures stable and precise audio signal transmission while minimizing electromagnetic interference. The NCF Clear Line-LAN also employs Furutech's proprietary Two-Stage Cryogenic and Demagnetization Alpha Process, ensuring unparalleled electrical conductivity and signal stability. This process strengthens molecular bonds in metallic parts and eliminates magnetization, enhancing conductivity and reducing distortion. The electrolytic capacitors, enhanced with a silver-colored damping treatment, effectively reduce vibrations and eliminate unwanted noise for crystal-clear sound. Experience immediate improvements in soundstage depth, balance, and harmonics, alongside reduced distortion and enhanced transparency.
Technology
Featuring 24k Gold-Plated Nonmagnetic LAN Connectors A specially engineered 24k gold-plated copper alloy EMI shield incorporated into the LAN connector provide more stable, clearer, and more accurate audio transmission. The excellent conductivity of gold can ensure more stable, accurate signal transmission stability, and consistency of audio signals. Reduced Electromagnetic Interference is essential for avoiding interference from electromagnetic noise in the surrounding environment.
Electrolytic Capacitor
Our electrolytic capacitors are engineered to optimize the acoustic performance of your devices. We've conducted extensive testing to select the ideal type and specifications of capacitor to elevate sound quality to its highest potential. The outer layer of our electrolytic capacitors is coated with a high-performance silver-colored special damping treatment, effectively suppressing unwanted vibrations, and enhancing sound clarity. Additionally, our capacitors feature advanced tuning technology designed to eliminate any noise interference originating from your equipment's output terminals, ensuring an unparalleled sound experience.
Specifications
- The screws of this product are fixed. Please do not disassemble or modify by yourself.
- We recommend aging for 24 hours or more.
- The carbon fiber pattern of the shell varies depending on the product. It is formed with composite carbon damping material and will only enhance the listening experience.

About Furutech
Furutech, founded in 1988, designs and manufactures an extraordinary range of A/V cables made with extremely high purity OCC single-crystal oxygen-free copper. 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.

The improvement in soundstage and instrument separation was amazing. Perhaps not surprising, given that it sits directly in the signal path. I followed this up by the purchase of an EE 8 Port audio grade switch. Though not directly in the signal path, it again made an improvement in the sound. So, when I saw a review of the Furutech LAN Optimiser, I thought, "Why not". It is plugged into a spare port on the EE Switch and, yet again, playing familiar recordings, the soundstage is firmer and instruments/voices picked out in more detail.
Before any of these devices were bought, I had spent time and money improving the mains supply with a dedicated "Hi-Fi" mains ring driving a 1500-watt balanced mains transformer. Various mains noise filters, etc., were also added, and ferrite rings were placed on all LED lamps, dimmers, etc. I suspect this helped allow the LAN devices to work their magic, which is what it seems to be.
