10 gauge with the BJC banana plugs will fit into the Axiom binding posts (unless they have changed them recently) and all other AV electronics.
I have personally assembled BJC locking banana plugs with 10 awg BJC speaker wire and since the BJC 10 awg is so thick you need a perfect strip on the wire because there is not much room in the gap where you are inserting the wire into the plug. If it is not a "clean strip" the strands will "jam" when you are inserting the wire into the plug and will cause it to slightly expand the tip. I had this same problem with a few I did an incompetent job on and they only fit part way into the binding post . I re-stripped the wire, re-assembled and then they fit fine.
The problem is that 10 awg is a boderline gauge wire to be used with the locking plugs. If you decided on the 12 awg, you wouldn't have run into this problem. Its totally fixable though.
