I like the things with braid but you are right the metal at the top needs shrink wrap. Who the heck designed those? Again the department of making shiny yellow metal appeal to the hobbyist. This is why I like the thing I recommended, use your own high performance wire of your choice, your choice of length and since the solder pot is large and the silicone shield fully covers the device it just works.
Instead of lopping if the banana which I could have used on the ads L1590/2 speakers, I used the jumpers to VE able to connect the 100-pound speaker without having to get to the connections on the bottom.
