Know before you buy
The technology uses nano-sized ceramic particles and powdered carbon to convert mechanical pressure into electrical charge. This active damping process helps eliminate unwanted resonance, resulting in a cleaner, more stable signal transmission.
While it does not require proprietary tools, you will need standard high-quality screwdrivers to secure the internal wire terminals and the outer housing. As with any high-end audio component, ensure you have proper wire stripping tools to achieve a clean connection.
Yes, the FI-50 (R) is designed for standard 15A 125V AC applications. It is a direct upgrade for most high-end power cords, provided the cable diameter fits the connector's internal housing dimensions.
The combination of nonmagnetic stainless steel, carbon fiber, and acetal copolymer creates a non-resonant housing. By minimizing mechanical vibrations and electrical interference, the connector ensures that the signal remains pure and free from coloration.
Absolutely. The FI-50 (R) is a popular choice for audiophiles building custom power cables who want to maximize signal integrity. Its robust construction provides a secure, low-resistance termination that outperforms standard industrial-grade connectors.
