Adding Furutech’s FI-11Cu high-grade copper IEC plug to your mains power cord will bring sonic benefits to your system for a relatively small outlay. This IEC will accept ultra-thick gauge cables and is easy to install.

    “The mighty Furutech”

    “One of the best, if not the best at this price point. The construction and appearance exude thoughtful design. I imagine a laboratory in Japan full of serious looking scientists working night and day making these things.”

    “furutech iec”

    “Excellent product and a great combination with the oyaide cable and MS copper plug. I reckon this combination can compete with much dearer ready made power cables. Overall a much cleaner sound with excellent sound stage and airiness around players. The IEC fits really well and looks great as well. David knows his cable and connector combinations.”
