AudioQuest SureGrip 300 BFA/Banana connectors fit a standard banana jack and wire up to 9 AWG.

Use AudioQuest SureGrip 100 Bananas to create a secure, high-performance connection between your speaker cable and loudspeakers. AudioQuest uses high-quality Beryllium Copper base metal, which is stronger, more conductive, and sounds better than the typical phosphor-bronze used in most connectors. Direct-Silver Plating looks great while avoiding sonically degrading intermediary layers of lesser-quality metal. The included mini-wrench creates a simple, secure cold-weld connection without requiring sound-damaging solder. Bare speaker wire is messy and unreliable. Compatible with universal speaker binding posts and cables up to 9AWG, AudioQuest SureGrip 100s create a clean, finished look while ensuring excellent sonic performance.

Sized for wire up to 7AWG and specifically crafted to complement our best-selling Rocket 44 and Rocket 88 speaker cables, AudioQuest’s 507 Banana Plugs are high-quality parts carefully designed for outstanding audio performance. Unlike common banana plugs comprising multiple pieces of inexpensive metals such as brass, AudioQuest’s 507 Banana plugs are fabricated from a single solid piece of high-purity Purple Copper. This is then treated to a Hanging Silver process in which the part is directly plated with high-purity silver, incorporating no sound-damaging intermediary layer. Taking performance further, AudioQuest’s Cold-Welded connection avoids the use of sound-damaging solder. AudioQuest’s Multi-Tool is included with every package of 507 Bananas. The Allen-wrench end allows secure tightening (Cold-Welding) of the electrical connection while the Phillips-head end allows tightening of the strain-relief screw. Available in Gold or Silver, in sets of four or six. Spade lugs also available.

AudioQuest Rocket 88 Bi-Wire speaker cable is the flagship model of the company’s versatile Rocket Series. It shares several outstanding design elements with its award-winning siblings, but significantly improves overall performance with its higher-purity conductor metal and patented 72v Dielectric-Bias System. Appropriate for bi-wirable speaker systems and terminated with high-quality silver-plated banana plugs, AudioQuest Rocket 88 is a high-performance speaker cable resolving enough for most high-end audio systems. Rocket 88 uses only AudioQuest’s very best copper, Solid Perfect-Surface Copper+ (PSC+), in a Double Star-Quad configuration designed to reduce distortion for cleaner, clearer, more naturally detailed sound. Like other models in the Rocket Series, Rocket 88 features AudioQuest’s effective Carbon-Based Noise-Dissipation, and, as with all AudioQuest cables, the conductors in Rocket 88 are Direction-Controlled to minimize the damaging effects of radio-frequency noise. Taking noise-dissipation even further, Rocket 88 adds AudioQuest’s patented 72v Dielectric-Bias System (DBS), which minimizes dielectric noise and improves wide-bandwidth dissipation of induced radio-frequency noise. Whenever possible, running separate cables to the treble and bass portions of a bi-wirable loudspeaker significantly reduces distortion. For these applications, an AudioQuest cable like Rocket 88 Bi-Wire keeps the large magnetic fields associated with bass energy out of the treble cable, allowing the delicate upper frequencies to travel a less disturbed path, like taking the waves out of the water when you swim. The result is smoother, clearer, more natural sound. With its thoughtful, time-tested combination of high-quality materials and design elements, AudioQuest Rocket 88 is an outstanding choice for high-performance audio systems.
