Viborg Speaker Spade Plug Connectors, Screw Locking Speaker Wire Connector with Allen Wrench+Heat Shrink Tubing, Fork Y Spade Lugs 45 Degree for Speaker Wire DIY 4PCS (Pure Copper Knurled Style)

Superb thats it

I purchased these spade connectors to replace some AdioQuest silver banana plugs which were constantly backing out from my speakers. I meant to purchase Viborg's all copper spade connectors but accidentally clicked on the rhodium plated ones. Rhodium, like gold, is resistant to oxidation but an even poorer conductor than gold (silver is best followed by copper). This turned out to be a blessing in disguise. I marked off the contact area(s) of the spade connector and filed off the rhodium plating, exposing the reddish copper. The plating is extremely thin and easily removed. The benefit of this is the exposed areas of the spade connector remain plated. Best of all there was no loss of sound quality.These connectors are well constructed. If anything, they are thicker than they need to be. They won't bend, are definitely pure copper, and your speaker wire will never come loose. You can find more expensive ones. While they may look nicer, I doubt you will notice any difference in performance. If you want to save a few bucks get the non-plated all copper ones. Unless you're using your speakers outdoors, oxidation shouldn't be an issue.

Fitted cables well, great finish, and with the shrink tubing gave a professional finish...

Used these spades because another set that I bought, to adapt bananas, for some unknown reason didn't work at all. I had an extra pair of these and they installed and performed just fine. I ordered two more sets to do ALL my connections.

High quality copper terminations at an excellent price, best suited for larger connectors.
