Looking for pure copper or Cu/Au bananas

Erik, the ones I linked you to are a great choice. I have used a plethora of brands over the years. These are the real deal and priced right.

The only ones that sound better are the KLEI bananas, but they are fragile and solder only. 

@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.
