True to its image as a "Haute Couture" designer of Audiophile accessories, 1877 PHONO offers us with its GC series banana plugs with a level of finish and quality of assembly far above average. Equipped with a main core entirely covered with 24k fine gold, itself overhung by a black matt tinted solid Aluminium clamping piece, these plugs have the particularity of having a particularly well thought-out locking system. Thus, when the body is screwed, it pushes a needle which spreads the end of the plug and allows an optimal contact preventing any untimely disconnection.
