I use the locking type banana plugs from blue jeans cable and they work excellent on both the binding posts of my axiom speakers as well as my receiver.
The spade lugs on the other hand from Blue Jeans do not fit on the bindings posts . This is common complaint from myself that have tried them and I have read this about them not fitting the binding posts from other manufacturers as well. So they are useless.
I highly recommend the locking type if you are going with a banana termination . Worth the extra money imo. They work great.
