The Furutech FA-aS22 bulk interconnect cable (aka Furutech FA Alpha S22) is the newest bulk interconenct cable by Furutech, and replaces the Furutech FA-220. This is Furutech's best/flagship bulk interconnect cable offering. The Furutech FA-aS22 uses Furutech’s α (Alpha) OCC conductor, which is known by audiophiles to be amongst the best conductor materials available for sound reproduction. Furutech's α (Alpha) OCC copper is made with high-purity oxygen-free copper using a special Ohno Continuous Casting process. Unlike regular OFC, almost all of the grain boundaries of this high-purity OCC have been removed at the micron level through a special casting process unique to Furutech.
The FA Alpha S22 uses a shielded twisted pair geometry, with each conductor insulated with a special grade of polypropylene. Each conductor leg is stranded @ 60 strands of 33 AWG material, for an aggregate AWG of about 15.3 AWG. The FA Alpha S22 then uses cotton dampening material, a paper sheath, an inner PVC sheath with carbon dampening particles, braided shield, and outer PVC sheath. Sold by the FOOT.
