Favorite banana plugs?

I like the simple low mass BFA style bananas over all other bananas and over all other type of terminal connection. Nordost Z-Plug is an example, but you can find really inexpensive options too. I prefer the super simple crimp-on version. I sometimes crimp and solder them on. Get some red and black shrink wrap to cover the exposed portion you don't push into the binding post. Just google "BFA Banana Plugs for many examples.

For me these were a game changer. Viborg Copper. Terminated onto Furutech-fs-a36 cable. Both after many plugs, they made a positive change in my system. I also made a set for another member, using the Silver plugs & he won't stop praising them!  

FWIW is find the locking banana plugs an unnecessary complication.
