Compare the Cardas Audio Dual Banana Plug and CPBP Clamp Modified for Bananas to decide which speaker cable termination fits your setup.
Quick answer
Choose the Cardas Audio Dual Banana Plug for a straightforward, high-quality termination or adapter, and the CPBP Clamp Modified for Bananas when you need to add banana plugs to a binding post system that already uses spade lugs.
Termination vs. adaptation: two different jobs
The Cardas Dual Banana Plug works as a direct cable termination or as a spade-to-banana adapter. Its non-magnetic eutectic brass and rhodium-over-silver plating deliver clean signal transfer, and the spring tensioner ensures a snug fit. The black plastic interconnect that holds the two plugs together is not fixed, so you can detach them for dual-mono setups.
The CPBP Clamp Modified for Bananas serves a different purpose: it is an insulator clamp drilled to accept a banana plug, designed specifically for Cardas' patented binding post system. This lets you use banana plugs on a speaker that normally takes spade lugs, without replacing the entire connector.
Installation considerations
Installing the Dual Banana Plug is straightforward: terminate your speaker cable with the plug or use it as an adapter by inserting a spade lug into the rear. No special tools beyond basic wire stripping are needed.
The CPBP Clamp requires you to work with the existing binding post clamp. It is a modification, not a plug-and-play cable end. If you are not comfortable disassembling your speaker terminals, the Dual Banana Plug is the simpler route.
Trade-offs at a glance
- Ease of use: Dual Banana Plug is a simple cable termination or adapter; the CPBP Clamp requires modifying an existing binding post clamp.
- Compatibility: Dual Banana Plug works with any standard banana jack or spade lug. CPBP Clamp only works with Cardas' patented binding post system. Check your speaker terminals before choosing.
- Signal path quality: Dual Banana Plug uses non-magnetic eutectic brass and rhodium-over-silver plating for low resistance. CPBP Clamp adds an extra connection point, which may slightly affect signal purity. If absolute signal path integrity is your priority, the Dual Banana Plug is the cleaner option.
