Oyaide C-237 20A IEC plug

Ultimate power transfer without compromise

The Oyaide C-237 20A IEC plug is specifically designed for high-end audio applications requiring maximum reliability, conductivity, and sound quality. What sets this plug apart is its unique multi-layer plating process: first, a thick layer of pure silver (1.5 microns) is applied directly to the polished copper surface. This silver layer then undergoes a second polishing treatment to perfect its smoothness. Finally, a fine layer of rhodium (0.3 microns) is applied to prevent oxidation and ensure a tight, controlled tonal balance. This precise combination of precious metals and finish directly influences the final sound reproduction: clear, fast, and with exceptional precision in the highs and midrange.

Like all Oyaide products, the C-237 is manufactured entirely in Japan, down to the smallest component. This "Made in Japan" approach isn't a marketing term; it's a guarantee of absolute quality control. By managing every step of the production process in-house, Oyaide prevents quality loss, micro-vibrations, and material degradation—common problems in standard components that negatively impact sound quality. The C-237's construction is designed for simplicity, stability, and ease of use: solid, precise, and safe to assemble.

The Oyaide C-237 is the ideal choice for serious audiophiles, installers, and high-end systems requiring a 20A IEC connector. Whether power cables for heavy-duty power amplifiers or high-end power filters, this connector guarantees clean power transmission without compromising sound. Choose the Oyaide C-237 if you're looking for an uncompromising, technically advanced, and sonically refined IEC connector. An investment in reliability and sound quality—as only Oyaide can offer.
