Image: Cardas CCMS S barrier spade
You might be able to scrunch the BFA contact so tightly into the milled copper Cardas CCMS S barrier spade with one .120" cable terminating hole that soldering it would not really be necessary. The Cardas CCMS S barrier spade looks very excellent and more robust than the Vampire BAR barrier spade (the Cardas barrier spade is more pricey, but likely the best barrier spade available) -- It may be the optimal audio dollar investment if you plan to use the speaker cables long term.
