I need top quality banana plugs.

I've got locking bananas from Monster Cable and Esoteric Audio. In fact, the Esoteric Audio are brand new. NOT silver. Gold plated. Yours for a song.

BTW: These will work with existing spades, so you don't have to destroy your factory terminated ends. I've also purchased some that you can use a set-screw to secure the cable within a barrel. If silver is a necessity, I would suggest soldering the cable INSIDE the barrel if so desired.

Rhodium is also a very good conducting material.

I believe in like metals, gold-gold for example. If your BPs are gold then use gold bananas. WBTs are locking and sonically excellent.

Interesting. Where does one buy WBTs?

Many thanks,
