I agree with the above post....Don't solder, CRIMP, and heat shrink them. Check out the Furez line of pure copper spades and bananas, which can be re-used on different wires you may be experimenting with. They use hex keys to tighten down to the wire with, and can be easily removed. If you don't like the wire you are experimenting with, you can re-use the terminations.
Best DIY silver solder?
I’m building some speaker cables... using spades for binding post connection. Any advice on the best value for silver solder?
