I had a similar problem to yours a year or so ago and wrote in. My Audioquest Rocket 88's were banana plug biwires and my then new Magico A3 speakers cannot be bi-wired.
The A3's speaker wire terminals could accept either a spade and/or a banana connector. An ingenious site member suggested putting one push on banana to spade adapter on one of the bi-wired Rocket 88's two black wires and another one on one of the two red wires going to each speaker. I then could put two wires into each terminal on each speaker.
No soldering, no fuss, no muss and works perfectly. I'd contacted Audioquest just like you and was put off by the cost. The four push on banana to spade adapters needed to do two speakers cost very little and solved the problem, enabling the bi-wire Rocket 88 to be used as a full range.
Don't know if this solution would apply to your situation, and hope I explained it adequately.
