Furutech Flux-C15 NCF Filter: inline power filtering for refined hi-fi systems

The Furutech Flux-C15 NCF Filter is an inline power filter designed for hi-fi systems, home cinema installations and demanding listeners who want to address mains-borne interference at component level. It is placed between a power cable and a power distributor, power strip or compatible device, making it a focused upgrade rather than a full system rebuild. In Furutech’s in-line power filter range, the Flux-C15 NCF is aimed at users who value clean power delivery, practical installation and careful control of electrical and mechanical noise.

Its design combines EMI filtering, a CF-C15 NCF(R) IEC connector and materials selected for conductivity and damping. The filter circuit uses coil and capacitor elements and is specified to attenuate noise components by around 8 dB at 100 kHz and around 14 dB at 500 kHz. Furutech also lists rhodium-plated α-treated conductors, α-OCC cable construction, shielding, flexible PVC sheathing with carbon powder and a nylon braided outer finish. Together, these choices make the Flux-C15 NCF a serious inline power filter for well-matched audio and video systems.

Use cases include connecting a suitable integrated amplifier, DAC, streamer, preamplifier, powered speaker or low-profile AV component where the IEC inlet shape and available space are appropriate. The slim C15-style connector is intended to help in tighter rear-panel installations, including some 4K/8K televisions and compact audio-video products. Always check voltage, current rating and connector compatibility before use, avoid cable strain and keep contacts clean as part of normal system care. Add the Furutech Flux-C15 NCF where targeted power filtering makes sense for your setup.
