I make all my own speaker cables. I use BFA style "banana" plugs. aka z-type. I use the simple crimp and solder type, either solid copper or silver plated. They don’t have a larger diameter insulated section to grab so I put 2 or 3 layers of shrink tube on to create a grabbing point.
I have been extremely happy with the sound through these connectors. they have a larger, firmer conducting surface and they are low mass (which many people don’t know, don’t care about, but I have been pursuing it and am happy with it).
