AudioQuest SureGrip 300 Speaker Connectors

The cold-weld system creates a permanent, high-pressure connection between the cable and the connector without the need for heat. This avoids the potential for solder-related signal degradation and ensures a more direct, pure path for your audio signal.

Yes, these connectors are designed to accommodate speaker cables up to 9 AWG in size. They are built to handle substantial, high-gauge wire comfortably.

Brass is often used in connectors because it is easy to machine, but it can introduce distortion. By using a purple copper base, AudioQuest eliminates those brass layers, resulting in a cleaner, more accurate signal transfer.

The POM (polyoxymethylene) casing is non-metallic, which prevents it from interfering with the electrical signal. It provides a protective, durable housing for the connector without introducing the distortion or capacitance issues that metal shells can sometimes cause.

The choice is largely a matter of preference. Gold plating is highly resistant to corrosion and oxidation, making it a great long-term choice for most environments. Silver is an excellent conductor, though it may require occasional cleaning if you live in an area with high humidity or air pollution.
