Yes, Audioquest makes a spade/banana adapter. I tried them as well as ones sold at Radio Shack. My system then sounded better with the Radio Shack adapters over the Audioquest. Do not know why. The RadShack ones are also less then half as much. I had bought the Audioquest ones at Audio Advisor.
Spade termination on speaker
I just purchased a new speaker cable (well over due). The old cables had banana that fitted into the speaker banana termination. The new cables are Coincident and have big spades at the end. I need to upgrade the termination on my speaker to put these spades in. Any one knows of a good termination to buy to put on my speaker? Where do I buy it from?
