NCF Clear Line RCA
Line Optimizer

Less noise equals more signal

After the great success of the NCF Clear Line AC, a line RCA version was inevitable. Simply insert the NCF Clear Line RCA into any spare RCA output or input terminal of your equipment – whether an amplifier, preamplifier, DAC, streamer, CD/DVD/SACD player, phono stage, etc. Plug and play!

You can opt to use a single unit, but you may also choose to plug in two – for example one per channel in the case of truly dual mono equipment – for even greater improvements.

You’ll notice the effects immediately, altough they have – like almost all audio accessories – a burn-in period. You will notice a significant improvement In the signal-to-noise ratio, you’ll experience an increase in detail and clarity, with enhanced reproduction of subtle nuances. The soundstage gains depth and is more vivid with greater contrast. Bass notes are tighter while the midrange and treble are sweeter and cleaner.

NCF Clear Line-RCA (NCF center pin multi-material hybrid structure)
The NCF Clear Line features a one-piece center conductor made of Alpha OCC with rhodium plating and is injected with Furutech’s special antistatic damping material ‚NCF‘. NCF features a special crystalline material that has two ‚active‘ properties. First, it generates negative ions that eliminate static. Second, it converts thermal energy into far infrared. Furutech combines this remarkable material with nano-sized ceramic particles and carbon powder for their additional ‚piezoelectric effect‘ damping properties of the housing.

Hybrid ceramic capacitors
These feature two audio grade ceramic capacitors (passive type) to enhance the musical performance of your devices. The Furutech design team has put in countless hours of testing to determine the perfect type and specifications of these capacitors to help you achieve the ultimate sound quality. The outer layer of the ceramic capacitors were coated with a high-performance silver-colored special damping treatment to suppress any unwanted vibration and boost sound clarity. These ceramic capacitors also feature advanced tuning technology that eliminates any noise interference induced from your equipment’s output terminals by shorting this noise to ground, ensuring that you get the best possible sound experience.

NCF Clear Line from Furutech by Paul Rigby @ TheAudiophileMan.com
„As such, these plugs and accessories like them can be sonic life savers. They can be the difference between making your HiFi usable or not. As simple as that. And because of that, the price is either extortionate or it’s worth every penny. Again, that depends on you and the performance of these plugs in your system.“

„Idle mind. Devil’s workshop. Open I/O. Noise“. „The underlying math is basic. Less noise = more signal“.

Japanese HiFi commentator @ Stereo Magazine Japan
I experimented with the NCF Clear Line RCA on the line input and output of my Accuphase Preamp C-2450. The effects using the line input terminal were outstanding, as follows:
– „The signal-to-noise ratio (S/N) improved, resulting in each sound becoming clear and distinct.“
– „There was an enhancement in transient response and dynamic control, leading to a dramatic improvement in the sense of power and liveliness.“
– „The transparency increased, making vocals and string instruments more melodious.“
– „The coloration disappeared, leading to a natural sound texture.“
– „The dynamic range expanded, resulting in a sound full of warmth.“
– „The overall sound became similar to an upgraded preamp or power amp, providing significant returns on investment.“
