Need help with cable termination!

Fellow Audigoners,

I need some tips on terminating my biwire Mogami 3104 speaker cables for banana plugs.

Mogami’s a four conductor cable, so at the amp end, we have to twist together the leads on two 12 awg wires to fit into each banana plug. It’s turning out to be a pretty challenging task, because there are few banana plugs with openings large enough to accommodate the stripped ends of the two conductors.

I initially used Vampire #SB compression screw plugs, since they do have a fairly sizable opening on the side, and after a bit of work, I was able to squeeze the wires into them. However, I decided to go with Furez TSTWP48XL,which is a crimp plug with back access. Since the Furez opening is a bit smaller than Vampire bananas, I’m having a devil of time trying to twist the two conductors to make them fit into the Furez plugs.

The Furez instruction sheet said to *not* twist the two conductors separately, but does anyone have any further suggestions to get the twisted ends as slender as possible? This is a kitchen-table project for me so I don’t have much in the way of a workshop, but is this something where I’m going to need to get a clamp vise and use pliers to twist?

Thanks for your help!
