The AudioQuest SureGrip BFA/Banana is made from Beryllium Copper with Direct-Silver Plating and a High-Pressure Contact System. Included will be a set of 4 Banana Terminals.
The SureGrip 300 connectors use Direct-Silver Plating over the high-quality Beryllium Copper base metal. SureGrip 300's use no underlying brass layers that would inevitably cause distortion and otherwise damage the sound. SureGrip 300's employ their effective Cold-Weld attachment system and feature an attractive non-metallic POM casing.
