Cold-Weld System for an ideal connection, better sounding than solder: Tighten Allen-screws with supplied tool to create an ideal connection between plug and conductor, then slide the no-magnetic-interference ABS casing over the banana screw into place.
Pure “Hanging” Gold plating directly over Purple Copper––no sound-damaging in-between nickel.
High-Purity Purple Copper provides cleaner and clearer sound compared to lesser coppers or brass used in other “premium” connectors.
