Speaker wiring
Strongly recommended by Vince, this cable uses an old braided wiring method that reduces capacitance drastically, up to 100 times less than parallel cables. Capacitance is above all what loudspeakers cannot tolerate, so if you do not use the Tress you are reducing your speaker's power.
The Tress carries oxygen-free copper wire 1.8 mm in diameter, insulated by a thick layer of Teflon. The metal parts are of the first quality: the silver is of great purity and the copper is extruded progressively, at reduced speed.
