Supra Cables Quadrax 2-4 bi-wire

摘要

Launched in mid-2011, Quadrax is the latest 'affordable high-end' speaker cable from Jenving's Supra brand, offered off the reel or in factory terminated pairs, including the gold-plated 'CombiCon banana plugs seen here. Like Clearer Audio's cable [p41], Supra's Quadrax comprises four separate conductors per cable so can be deployed in bi-wire, bi-amp or, doubled-up, as a 2-2 stereo cable with half the resistance. Measured in 2-2 mode, the pairs of 2mm2 conductors (multiple tin-plated copper strands) offer a low 9mohm/m resistance, and 0.23μH/m inductance although the 19Mohm leakage does suggest some slight dielectric loss.
