I cut out the edge of a box and slid the end of the cable inside the corrugated piece and then just put some electrical tape over it to protect the connection.
So basically one side is connected and one side isn't and according to the cable manufacturer, transparent, it shouldnt matter. But I tend to think cutting the gauge effectively in half is not a good thing.
when You have really expensive cables it's kind of hard to sacrifice the biwire end. And also when you biamp, it's twice as many cables. It's not a perfect world.
Don't really hear any difference it would be nice if I had the full gauge of the cable available.
