Know before you buy
The connector features a compact, low-profile design specifically engineered to fit into recessed or tight IEC sockets where standard, bulkier connectors cannot reach. It is an ideal solution for equipment like Devialet, LINN, or McIntosh amplifiers that have limited clearance around the power input.
NCF (Nano Crystal² Formula) is a specialized material that generates negative ions to eliminate static electricity and converts thermal energy into far-infrared radiation. In practice, this provides superior electrical and mechanical damping, which helps reduce noise and improve the clarity of your audio signal.
The FI-C15 NCF accommodates power cables with an outer diameter ranging from 6.6mm to 16.0mm. Internally, it supports wire gauges up to 3.5mm², or 12AWG.
Rhodium plating is known for its exceptional durability and resistance to corrosion. Sonically, it is often described as providing a very clean, detailed, and transparent sound profile compared to other plating materials.
Yes, the connector is rated for 15A at 125V and 10A at 250V, making it suitable for standard high-end audio power applications in both North American and international markets.
The cable is secured using a reliable set-screw termination style. This ensures a tight, vibration-resistant connection that maintains consistent signal integrity over time.
