Looking for pure copper or Cu/Au bananas

Look at  DH Labs pure copper and 2 screws for good physical contact .

I think I've settled on a good, relatively affordable set:

Back when I purchased my Furez bananas, I contacted Furez, told them what I wanted, and purchased directly from them. As mentioned above.......I like the products very much. Those Furutech bananas have " lots of different metals ", for what it's worth.

@mitch2 Only 1 in stock, need 2.

That is strange Eric - I loaded 2 and then 4 sets into a cart and they seemed to be in stock.  However, the AECO bananas you chose look pretty good too.  Tellurium Copper adds durability over pure copper and is typically listed between 90-95 percent IACS, which is much better than the other copper alloys sometimes used, which are Phosphor Bronze at about 48 percent IACS and Beryllium copper at about 30-38 percent IACS. 

I was fortunate to purchase a bunch of the set screw style Furez copper spades and copper bananas (like these) before the pandemic.  I don't know why Furez seem to have stopped production of those because they were/are pretty nice.  The larger sized bananas and spades they formerly offered were also useful because they accommodated the larger 7awg cables I have made.  I also like the rubber inserts inside the bananas that seem to add stability and damping, and resist deformation.

These are great. Use double walled, adhesive lined heat shrink tubing over the barrel as your finishing touch. Sound good and lock in very securely. Build quality is high.
