Furutech Reference III- N1 Speaker Cable - Pair (3.0M) High End Performance Speaker Cable for Audio EquipmentAll metal parts are treated with the※FURUTECH α(Alpha) Process (Super Cryogenic & Demagnetizing Treatment) Features Double-shielded α (Alpha)-OCC Conductors eliminate radiated noise•Formula GC-303 Antimagnetic EMI-Absorbent Modules surround each cable•High performance beautifully engineered and finished rhodium plated pure copper spades•FP-201 (R) Spade terminals nonmagnetic rhodium-plated pure copper (Nonmagnetic rhodium-plated eutectic cast brass FP-202 (R) Banana connectors by request).•Insulated with air-foamed Irradiated PE reducing capacitance and damping vibration•Results in greater resolution, clarity, powerful dynamics, and an ultra-quiet soundstage in which music develops more fully without artificial upper-frequency “presence region” glare.•GC-303 allows a deeper, tighter bass to form a solid foundation for the rest of the frequency range, better defining the original recording’s venue. Natural, unforced detail reveals nuance and energy for an engaging musical experience.α (Alpha) Conductor Is Composed Of Fine PCOCC Wire StrandsTreated With Furutech’s α (Alpha) Cryogenic and Demagnetizing Process Specifications Specifications: Construction and Materials•6 bundles of 20-strand α (Alpha)–OCC Conductor・0.18mm, 2.7mm diameter: Wire AWG: 3.0 SQ.mm / Over 13AWG•Insulation: Air-foamed Irradiated PE (Red/White) 5.1mm diameter•Cable Lay: Two twisted cores•Sheath: Two layers flexible PVC (Purple/Red) 13mm diameter•Shield: Special EMI- and noise-absorbent Formula GC-303 module•Jacket: Nylon yarn braid approx. 14.5mm•Connectors: Spade Terminal [FP-201 (R)] or Banana Connectors [FP-202 (R)]Electrical Properties of Cable Test MethodMax.
