Looking for pure copper or Cu/Au bananas

@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.

@rixthetrick 

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,

@grannyring my speaker binding posts are ETI, might swap out the ones on my amplifier to match as well.

grannyring what XLR connectors would you recommend to try out?
Sorry erik_squires - not trying to spoil your thread.
