AudioQuest SureGrip 300 Spade

The cold-weld system creates a secure, permanent connection by physically compressing the wire into the spade without the need for solder. This avoids the potential for heat damage to the cable and prevents the introduction of dissimilar metals that can occur with soldering, ensuring a cleaner signal path.

Purple copper is a high-purity material that offers superior conductivity compared to brass. By eliminating brass layers, these connectors avoid the distortion often associated with lower-quality base metals, resulting in a more transparent and accurate audio signal.

These spades are designed to accommodate speaker cables up to 9 AWG. If your cable is thicker than 9 AWG, it will not fit properly into the termination point.

The POM housing is non-metallic, which is a deliberate design choice to prevent the housing itself from interacting with the signal or causing interference. It serves primarily as a durable, protective shell that keeps the connection stable and aesthetically clean.

Both options provide excellent corrosion resistance and conductivity. Direct-Silver is often preferred by audiophiles for its slightly better conductivity, while Direct-Gold is chosen for its superior long-term resistance to oxidation and tarnishing in humid environments.
