About the Clear Line-USB

The Furutech NCF Clear Line-USB is a passive line optimizer designed to improve digital audio performance when plugged into available USB ports on preamps, DACs, AV receivers, or streaming players. It features 24k gold-plated nonmagnetic USB connectors with a copper alloy EMI shield for stable and accurate audio transmission, reducing electromagnetic interference. The device incorporates Furutech's Nano Crystal² Formula (NCF) material for superior damping, which generates negative ions to eliminate static, converts thermal energy to far-infrared, and provides piezoelectric damping effects. Additional construction includes a semi-sealed air chamber with an electrolytic capacitor for vibration elimination, a housing body ring of resonance-damping stainless steel and NCF, 4-layer hybrid NCF forged texture carbon fiber housing, NCF end cover of heat-resistant nylon and NCF, and anti-shock stainless steel security screws. All metallic parts undergo Furutech’s Two-Stage Cryogenic and Demagnetization Alpha Process (-196 to -250°C freeze followed by demagnetization) for optimal conductivity and stability. Benefits include immediate improvements in S/N ratio, soundstage depth, focus, harmonics, balance, transparency, high-frequency noise reduction, contrast, distortion reduction, and clarity. Recommended burn-in time is 24 hours. It is currently manufactured and available.
