I started with some Belkin hybrid speaker cable. You will notice there are multiple types of conductors:
1-flat, 1- large, 4-medium and 12-small (individually insulated). Connectors are BFA Banana .
I made a pair of "shotgun" speaker cables using Bently Harris expandable sleeve.
I ran out of the barrel banana plugs so swithced to standard banana for the common end.
