Looking for pure copper or Cu/Au bananas

@grannyring

Thanks so much! Those are exactly what I’m looking for.  Sorry I missed your original posting.

@grannyring - there’s some history between Keith Eichmann and ETI, which is why they are rather similar in may ways.

Have you personally tried the ETI Research LINK Banana plugs?
I am curious, these have double screws.

Also, have you any personal experience with the ETI Kyro connectors (stupid expensive I know), in particular XLR? I understand from a mutual friend you are very
well versed and experienced in connectors, and cables.

At first, I thought, at this price, if it's junk, I'll return it.

Everything I have ordered from wish and ali has been genuine high quality parts, I adapter posts, spades, bananas, cables, locking connectors, ....

try something in-expensive just to learn, return if junk. you will be very happily surprised.

I have used ETI RCA plugs only. I liked then.  In the end I liked the KLEI just as much for lower cost. I have not tried their bananas and bet they are very good! 
 

The Viborg option was based on the great value they represent. Good sound and affordable.  

Parts Connextion is a good choice for adhesive lined heat shrink.  I have had good luck with these also,
