I own Purist Audio Venustas biwire speaker cable in 1/4" spades and am working with Purist to make up some jumpers in bananas to jump from the mid to the tweeter ( I assume this would be the best way to go). I have ordered some IB1's and wonder how the factory jumpers are. Anyone using other jumpers outside of the factory ones and will a regular banana work or is it better to go with some WBT 0644's for example? Thanks. Dave
