AudioQuest 507 Series Multi-Spade Speaker Connectors (Set of 6)

The AudioQuest 507 Series Multi-Spade Plugs are designed as high-performance speaker connectors for rigorous stereo or home-theatre systems. Engineered to handle heavy-gauge speaker cables (up to 7 AWG), they offer a robust, low-resistance connection that helps preserve signal fidelity from amplifier to speakers. Their build quality and precise termination method make them a top-level choice for audiophiles who demand stability and clarity from speaker wiring.

One-Piece High-Purity Purple Copper Body for Uncompromised Signal Integrity

Each 507 Multi-Spade plug is machined from a single piece of high-purity Purple Copper rather than assembled from multiple parts or low-grade metals. This solid-body construction ensures a consistent electrical path and minimizes resistance or contact-related distortions. The result is a clean, transparent transfer of audio signals that helps maintain dynamic range, tonal balance, and detail — giving your speakers the best opportunity to perform at their peak.

Direct Silver or Gold Plating Without Intermediary Layers for Clean Contacts

The contact surfaces of the 507 Multi-Spade are directly plated with high-purity silver or gold, avoiding intermediary, lower-quality layers (such as nickel) that can degrade signal quality. This direct-plating method reduces contact resistance and helps prevent sonic coloration or signal loss at the connection point. For audio systems aiming for neutrality and transparency, this ensures the connector does not become a weak link in the signal chain.

Key Features
  • Solid one-piece high-purity Purple Copper body — ensures a clean, low-resistance conduction path
  • Direct silver or gold plating with no intermediary metal layers — preserves signal purity at contact points
  • Cold-weld clamping termination — solder-free, secure connection that resists oxidation and loosening
  • Supports up to 7 AWG speaker cables — suitable for high-power, high-current applications
  • Compatible with standard binding posts — broad compatibility across amplifiers and speakers
  • Suitable for stereo, bi-wire, or bi-amp configurations — flexible wiring options for varied audio setups
