Audioquest Spade 507 Speaker Connectors
Best high-fidelity upgrade for audiophiles seeking a secure, pure signal path.
The AudioQuest Spade 507 Speaker Connectors are engineered for superior audio fidelity in your system. They feature a solid, one-piece construction using high-purity Purple Copper, avoiding inferior multi-piece designs or brass. The connectors boast an especially pure "Hanging Gold" plating applied directly, eliminating intermediate layers that can degrade sound. Connection integrity is ensured via a cold-welded process instead of standard soldering. These versatile spade connectors are designed to fit standard banana plugs and securely accommodate speaker cables up to 7 AWG for a reliable, high-quality signal path.

What customers say
Audiophiles overwhelmingly praise the Audioquest Spade 507 connectors for their exceptional build quality and significant sonic improvements. Users value the robust construction and the secure, solderless connection achieved through the cold-weld system, which minimizes signal loss. The core satisfaction driver is the resulting audio enhancement, with many reporting clearer sound, tighter bass, and a more defined soundstage. While the spade design offers a reliable interface with binding posts, the premium price is noted as substantial. Despite the cost, the consensus is that these connectors deliver tangible acoustic benefits, making them a worthwhile investment for those dedicated to maximizing high-fidelity system performance.
Know before you buy
Purple Copper is a higher-purity material that offers better conductivity than brass. By using a solid, one-piece design, these connectors minimize signal resistance and avoid the sonic degradation often caused by the multi-piece construction found in cheaper alternatives.
The 'Hanging Gold' is plated directly onto the copper, which eliminates the need for intermediate nickel or other metal layers. This direct application ensures a cleaner signal path and prevents the sound quality issues that can arise from layering multiple dissimilar metals.
Cold-welding creates a permanent, high-pressure physical bond between the cable and the connector without the use of solder. This method maintains the integrity of the cable's metallurgy and prevents the signal loss that can occur when heating metals during the soldering process.
Yes, the 507 connectors are designed to accommodate speaker cables up to 7 AWG. This makes them a robust choice for most high-end, heavy-gauge audiophile cables.
These spade connectors are specifically designed to be compatible with standard banana plug terminals. They provide a secure, high-contact surface area that ensures a reliable connection for your audio system.
