biwire terminations

Thanks for your insights. I guess this setup would also limit the resale possibility somewhat...

I own speaker cables with this style of banana plug (not this brand, but the style of connector) on one end and spades on the other. I don't know the appropriate name for the style of banana plug, but they connect in a very solid manner. They do not slip, slide or move whatsoever, and it takes firm effort to remove them from binding posts.

Spades act like electrical dams. Bananas provide the least damming effect. When biwiring, it is preferable to go one set bananas the other spade- or better still sans spade

Many of the Tara Labs speaker cables have interchangable bananna and spades that screw into the cable termination. So you can have it both ways.
