WBT Banana Connectors

This thread is bringing out the technical challenges  of banana connectors.  Traditional bananas are often gold plated steel (yes steel) as springs are needed to make them expand in the "banana" section.

Solid silver and copper (such as ofc) are very soft.  KLEI is one of my favorite connector manufacturers.  they make low mass, high conductivity connectors.  but solid copper won't be strong enough with a heavy cable.  

I like the tellurium copper with heavy silver plating (tellurium alloy copper is not quite as conductive but much stronger than pure copper).

Go Spades.

My bad. Thank you! Many things are better when tight!!

I’m worried about the weight and stiffness of the cables too, and also managing what to do on the back of the Marantz with the small spring connections.

Pin to Spade or Pin to Banana. Leave the backend of that Marantz alone (original) unless you’re eager, willing, daring and have the technical know-how for such a mod. Reconfigure your rack to where the 2270 could / can be set close to the floor in order of cable support, or support cables with various technics. You’ll want to relieve sag! Trust me, I have a Marantz 2270 ....
