Eliminate unwanted resonance derived noise from your AC power

A new addition to Furutech's NCF range, the NCF Clear Line is an AC power optimizer that instantly improves the quality of the electrical signal supplied to your audio/video devices and therefore offers better reproduction. Very easy to use, simply plug the NCF Clear Line into a free power outlet of a power strip. For optimum effect, it is recommended to use the NCF Clear Line on the same power line as your A/V system. The result is an expanded sound stage, a beautiful balance of timbres and convincing harmonics. The low frequencies are also cleaner and the background noise level is reduced.

It takes just a moment to hear the difference that Furutech’s NCF Clear Line can make to your audio or video system. Why just a moment? Furutech Nano Crystal² Formula (NCF), also known as NCF, has resulted in a number of truly innovative and effective products over the past few years. NCF features a special crystalline material that has two distinct properties: it generates negative ions that eliminate static, and it converts thermal energy into far infrared. Created by Furutech, NCF is found exclusively in Furutech products and nowhere else.

Now, Furutech has introduced perhaps the simplest way to implement NCF technology into your home. NCF Clear Line, which is an audio grade AC optimizer, small enough to hold in your hand, that instantly enhances the quality of your power supply. Its body is formed with nylon and glass fiber incorporating nano-sized ceramic particles and carbon powder for their additional "piezo electric" damping properties. It incorporates two enameled "Alpha-OCC Air" passive wire coils to improve power quality and overall system performance. For best result, use the NCF Clear Line on the same AC line/supply as your system, preferably at a receptacle adjacent to your system.

You will instantly hear the improvement in the sound. You won’t have to switch back and forth repeatedly in order to “discover” an improvement. It’s right there. You’ll immediately notice improvements in the depth and focus of the sound stage, harmonics and tonal balance with NCF. Low frequencies are cleaner, with a greater sense of definition made possible by a lowered noise floor. Then unplug the NCF Clear Line from the power receptacle. You’ll immediately miss those sonic improvements. You’ll want them back.

In home theater applications, you will also hear these same distinct results. Just as importantly, you’ll see the difference in your video quality. All you need to do is plug the NCF Clear Line into your home entertainment system and the improvements will be instantly noticeable. Sharper. Clearer. Yet more natural and easy on the eyes.

The NCF Clear Line Optimizer simply takes your listening and viewing experience to the next level. Find out for yourself. It Improves resolution, focus and 3-dimensionality of performance.

Furutech NCF Clear Line AC Power Line Optimizer review, A skeptic gets his comeuppance by Paul Schumann @ enjoythemusic.com
“As soon as I started to listen to this piece with NCF Clear Lines in place, I was able to easily pick out the soloist and hear how his part intertwines with the rest of the ensemble. Once again, throughout the entire disc, I felt more connected to the music.”

“Take away the NCF Clear Line and the voice becomes less intelligible, the music somewhat messy, squeezed into a shallower soundstage. Exaggerated? Sure, but I want to make clear what I experience.”

Furutech NCF Clear Line Power Supply Optimizer by Marc Phillips @ PartTimeAudiophile.com
“The Furutech NCF Clear Line is one of those products where you hold it in your hand and wonder why it costs as much as it does. Then you hear the effect such a product has on your system, and you say to yourself that this is the best € 250 you’ve ever spent in audio.”

“You won’t be able to remain a tweak cynic when you hear this!”

A no brainer Review by Reviewer and tweak expert John van Polen
I own two stereo systems, one full range high end and the other somewhat scaled down. Both are equipped with a NCF Clear Line AC Optimizer now. I perceive the audible result as nothing short of spectacular! The sound is more relaxed now; less stress, even when playing demanding music. Musical lines and details I never heard before come to the surface. Futhermore, the NCF simply kills all unnatural sharpness. By the way, in the high end system, some break-in was necessary. The first day, the sound was somewhat weak and warm. Two days later, dynamics was fully restored and the system sounded more accurate and refined than ever. Besides, acoustic musical instruments are presented in a more realistic fashion now. In short, at the moment I am not aware of any accessory having a better performance-price ratio than this little AC plug. A no brainer, really. (Posted on 1/21/2021)
Highly recommended! Review by Ton
I ordered the Furutech NCF clear line and I’m very happy with the results it delivers. More spacious 3D sound, more micro-detail and less harshness. Connecting the NCF clear line to my power strip even gave a further improvement over connecting it to the wall outlet. So highly recommended!
