"You can use them with one end on the amp and the other TWO on the speaker terminals. No advantage. No disadvantage except the clutter."

I do this and it works. I went from passively bi-wired Paradigm Studio 100 V3's to "regular" wired speakers, and now the spades are stacked at the speakers' binding posts. I thought I'd need new cables, but didn't. No problems. By the way, in my old setup, the biwiring, even though passive, did open up the soundstage a little bit as compared to "conventional" wiring.
