ZU audio Libtec speaker cable

ZU audio Libtec speaker cable, length 1.75m, made in the USA. When buying, it had connectors: a speakon and copper plugs (indicated on the box). For better sound and convenient connection, I replaced it with: WBT-0681CU and DH Labs Banana Locking-2 Plug Silver. Can sell without connectors for 115.00 euro.
