SFB Refv2 Reference Banana plugs
The Soundfoundations Refv2 banana plugs are the ultimate connectors you can buy for your high-end speaker cables
Their copper plugs are True rhodium coated to add that “sweetness” to the musical presentation as opposed to the general gold plating
They are lock-able plugs whose tip expands as you rotate the barrel giving a very tight connection to the binding post.
They also feature a larger entry hole diameter to accommodate those THICK speaker cables
