Furutech are a manufacturer of ultra-refined analog, digital and video cables. They also specialise in creating high performance audio accessories and power cables.
The Furutech FI-09G is a high-performance, gold-plated IEC inlet with gold-plated contacts. It is an extremely high-quality IEC inlet, with all metal parts made from copper using the Alpha process prior to gold-plating. It employs a heavy-duty wire-clamping mechanism that allows the use of up to 4mm diameter bare wire, and is constructed from a very rigid nylon/fibre-glass mixture that is acoustically inert.
This IEC inlet is slightly larger than the customary inlet, so a standard IEC hole may have to be enlarged to fit these.
