The AudioQuest SureGrip 300 Banana Plugs are high-quality connectors designed to ensure a secure and efficient connection between speaker cables and audio components. Made from high-purity beryllium copper, they offer superior conductivity compared to standard brass connectors. The plugs feature a direct-gold plating that eliminates a typical layer of distortion-causing nickel, preserving signal integrity. A cold-weld system and high-pressure contact design provide a tight, durable connection without the need for solder. These plugs are compatible with standard 3/4" (19mm) spacing and support cables up to 9 AWG, making them ideal for audiophiles seeking uncompromised performance.
