banana= spade adapter for Wireworld speaker cable

I recently purchased a pair of Wireworld Eclipse speaker cable with banana termination on both ends.
But, one of my amps only take spades. So, I need to find the banana to spade adapters.

Does anyone know where I can purchase these adapers? Or, Do such adapters even exist?

Many Thanks
Don't know about the adapters but why not have Wireworld re-terminate the cables?
Try here:
these work great. the ends are machined smooth and accommodate banana plugs perfectly
do they have the other way around...spade to banana?
