Furutech Power Reference III
High-end mains cable from Furutech, featuring Alpha-treated conductors and Rhodium-plated connectors, for a refined power supply to audio equipment.
Description
The Power Reference III is a high-end mains cable designed by Furutech for powering audio equipment. It belongs to the Japanese manufacturer's Reference series, known for its careful machining and materials selected for quality electrical transmission.
This cable incorporates GC-303 modules, electromagnetic interference (EMI) absorbers specific to the Reference series, designed to limit interference that can affect the electrical signal transmitted to connected equipment. The conductors are treated using the Alpha (α) process, a proprietary Furutech treatment aimed at improving the structure of the copper used. The special polyethylene insulation is stated to be resistant to high voltages and heat, with the intended effect of reduced capacitance and improved mechanical damping of the cable. The connectors are Rhodium-plated, a metal valued for its resistance to oxidation and good contact conductivity.
This type of mains cable is aimed at audio enthusiasts wishing to refine the power supply to their high-end equipment: amplifiers, players, DACs or other sources sensitive to mains power quality. It is particularly relevant for systems where the user seeks to optimise every link in the chain, including the power supply.

What to check before buying used
The pin connectors should be checked one by one: any play or oxidation here negates the entire benefit of the Rhodium plating. The sheath and braiding deserve a visual inspection along their full length, looking for pinching, cuts or crush marks that could compromise the shielding. It is also worth checking that the GC-303 modules are firmly attached to the cable, with no play or cracking at their fixing points.
