I had bad experience with Furutech locking bananas with rhodium plating. 2 things happened:
1 - They diameter of the plugs were subtly but importantly undersized. Maybe 2 millimeters. This meant that on some speakers they simply would never be tight enough. Focals in my case then.
2 - They permanently deform very easily.
Rhodium is honestly too hard a material. You want something soft that will allow it to bend to the shape of the mating metal. WBT’s locking bananas are far superior. They are noticeably tighter even when closed, and do not deform even after multiple insert/remove cycles.
I looked at the KLH plugs. I’m sorry but solder is not a good way to connect speaker cables to speakers. You want to use the crimp sleeves with a lot of pressure, and insert those into your WBT plugs or similar. The spring loaded spades or bananas are great.
