Know before you buy
The silver plating is used to enhance electrical conductivity and signal clarity. It helps provide a more transparent, high-resolution sound profile compared to standard nickel or brass connectors.
The FI-11-N1 is compatible with cable diameters ranging from 6.6mm to 16.0mm. If your cable is thicker, up to 20mm, it can still be accommodated by using a longer screw.
This is a proprietary Furutech design that prevents induced magnetic fields from interfering with the electrical signal. By grounding the metal parts of the connector, it reduces noise and distortion for a cleaner audio output.
No, the connector uses a standard screw termination style. You will only need a screwdriver to secure the wires to the internal terminals and to assemble the outer housing.
The use of α (Alpha) Phosphor bronze and a rigid nylon/fiberglass housing helps minimize mechanical resonance. This stability ensures that the power delivery remains consistent, resulting in tighter bass and more precise high-frequency detail.
Yes, it is rated for 10A/250V A.C. or 15A/125V A.C., which is sufficient for most high-end audio components, including power amplifiers and integrated systems.
