FURUTECH FI-E38 (G)

The Furutech FI-E38(G) is a Schuko mains plug developed according to the Japanese brand’s Pure Transmission philosophy, which focuses on every aspect of power transfer to minimize losses, interference, and distortion. Every construction detail is engineered to optimize current flow, enhancing connection quality and ensuring outstanding performance in the most demanding high-end audio systems.

The FI-E38(G) features pure copper conductors treated with Furutech’s proprietary Alpha α process and finished with gold plating, a combination that delivers excellent conductivity and remarkable resistance to oxidation. The Alpha α treatment consists of two stages: a deep cryogenic process at -250°C using liquid nitrogen, which helps stabilize the metal’s molecular structure and improve its electrical characteristics, followed by exposure to a powerful controlled magnetic field that eliminates residual magnetism, allowing the conductors to achieve their optimum performance.

Among the most advanced technologies incorporated into this connector is the patented Floating Field Damper System, an evolution of Furutech’s renowned Earth/Ground Jumper System. This technology is specifically designed to reduce floating magnetic fields and electrostatic charges that can develop within metallic connector components during current flow. Such phenomena may introduce electrical noise, micro-distortion, and unwanted resistance that negatively affect transmission quality. The system strategically links key internal metal components through a dedicated conductive structure that channels unwanted energy to ground, stabilizing electrical potential and contributing to cleaner, more stable, and more efficient power delivery.

The FI-E38(G) housing is constructed from a durable nylon and fiberglass composite enriched with carbon particles, providing excellent mechanical strength and effective absorption of vibration and resonance. This robust structure also offers outstanding resistance to impact, electrical arcing, and high temperatures, ensuring long-term reliability and operational stability.

The conductors are secured by three dedicated terminals for live, neutral, and ground connections, identified by color coding for easier installation. Furutech’s exclusive Wire Clamp technology, combined with a specially engineered pressure plate and metal cable clamp, provides an exceptionally secure grip on the cable, preventing accidental loosening while significantly increasing the electrical contact area. This design also helps reduce both mechanically and electrically induced distortion, ensuring a stable and reliable connection over time.

Compatible with cables ranging from 6 to 17 mm in diameter, the FI-E38(G) measures 56.6 mm in body length, 39.6 mm in diameter, and 88.7 mm in overall length. Rated for operation up to 16A and 250V AC, it represents an ideal choice for audiophiles seeking to build high-performance power cables capable of maximizing both sonic quality and system reliability.
