NCF Clear Line USB-A
Line Optimizer

Less noise equals more signal

After the great success of the NCF Clear Line AC, RCA and XLR, a digital USB version was inevitable. Simply insert the NCF Clear Line USB into any spare USB-A input or output terminal of your equipment – whether a streamer, DAC, settopbox, TV, etc. Plug and play!

This USB connector from Furutech’s NCF Clear Line range is designed to optimize the audio signal. It is a Plug & Play device, and aims to improve the signal-to-noise ratio (SNR) and dynamics for a more transparent sound. This NCF Clear Line USB is dedicated to the USB-A ports of your devices. This optimization is made possible by the use of electrolytic capacitors and carefully selected non-magnetic materials.

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.

An electrolytic capacitor
Furutech’s Clear Line USB is equipped with an electrolytic capacitor to enhance the performance of your devices. It is coated with a special high-performance damping treatment, eliminating unwanted vibrations. Interference from your devices’ input and output terminals is also eliminated.

Alpha (α) treatment
All the metal parts that make up the Clear Line USB benefit from the brand’s two-stage Alpha cryogenics and demagnetization process. First, the parts undergo deep cryogenic freezing via high-end refrigerants such as liquid nitrogen or helium. Once temperatures of between -196 and -250°C are reached, the parts are subjected to internal stress, tightening the molecules of which they are composed into tighter bonds, resulting in a more stable overall structure and improved conductivity. In a second step, the various mechanical parts are exposed to a ring demagnetization treatment patented by the brand.

High quality construction
The USB-A connector of the Clear Line-USB is covered with a 24k gold-plated copper alloy EMI shield, protecting it from oxidation and electromagnetic noise. Furthermore, the internal air chamber that receives the electrolytic capacitor is sealed under pressure for further damping effects.

Description of components
The outer casing is made from non-magnetic stainless steel and a composite of carbon fibre and NCF (a crystalline material developed by Furutech). Finally, the NCF cover is made from a special heat-resistant nylon and Furutech’s NCF material for improved efficiency and damping effect.
