Looking for pure copper or Cu/Au bananas

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.

I like the Vampire XLR connectors at Parts Connextion for the money. Pure copper and solidly built. If you have the budget, then I bet the ETI’s would sound a bit  better.

I only used the Vampire in my builds as they represented great sound at reasonable cost. 

Vampire is out of business, and the PCX stock is, AFAIK, the very last of it.

Neutrik makes very affordable XLR’s with silver contacts, and I use them exclusively. Now that I’ve simplified my gear though I only have 2 analog line level connections:

• XLR cables between my DAC and integrated.
• RCA cables between the AVR and the integrated for which I use Eichmann bullets for.

Wow! Just looked.  Interesting.  The DH Labs is the same part based on my use of them when Vampire was out of stock. They are equally good. PC has far too many out of stocks.
