MCRU customer review by Craig Cook (verified owner) – 29th October 2020
Excellent “inexpensive” boost in SQ for all High end systems who do not have the benefit of a stand alone mains power supply. Definitely lowered the noise floor in my system which had the effect of deeper more articulate bass lines, much wider soundstage and more space between the vocalist and instruments. Give it 24 hours to “break in”. I just plugged mine into an empty socket on my Nordost QB6. Highly recommended.

You will hear the difference immediately:

Furutech’s Nano Crystal² Formula, 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.
When combined with nano-sized ceramic particles and carbon powder, these crystals become the ultimate electrical and mechanical damping material. 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—The NCF Clear Line.
The NCF Clear Line is an audio grade AC optimizer, small enough to hold in your hand, that instantly enhances the quality of your power supply. Simply plug the NCF Clear Line into any vacant receptacle on either a power distributor or wall outlet. For best effect, use the NCF Clear Line on the same AC line/supply as your system, preferably at a receptacle adjacent to your system.

It only takes a moment to 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.

Take your listening or viewing experience to the next level with Furutech’s NCF Clear Line. Just a moment and you'll find out for yourself.

Furutech’s Two-Stage Cryogenic and Demagnetization Alpha Process
Using cutting-edge technology and materials, Furutech developed a low-temperature two-stage process that significantly improves every facet of audio and video performance.
The treatment begins during the manufacturing process with a deep, conditioning cryogenic freeze of all metal parts. Using high-end refrigerants -- liquid N2 or He -

 

- Furutech achieves temperatures of between -196 to -250℃. The treated parts change their molecular structure at these extremes of temperature, relieving internal stress. The molecules bond together more tightly and the overall structure becomes more stable. This improves electrical conductivity and therefore power and signal transfer.
Step two in the Alpha Process exposes these same parts to the patented Ring Demagnetization treatment. Ordinary high-power magnets used for this purpose often increase magnetic effects; they leave some areas more magnetized than others. This patented process uses controlled attenuation to completely eliminate magnetization for more vivid and colorful improvements to sound and picture quality. Ring Demagnetization further enhances conductivity of all treated materials.
ALL metallic parts used in Furutech products go through the Alpha Process treatment to keep all connectors, conductors, and metal parts in a perfect stress-free, stable, and highly conductive state.
