What is this speaker cable connection?



I was given these speaker cable and told these were really expensive. But when look at the connection, it doesn't make any sense to me. I have used banana plugs before. But I have no idea how to connect these with my amplifier. Any help would be greatly appreciated. 
What is your amplifier?
Well, not sure how expensive those connectors are in real life, but they are just typical spades. Unscrew the amp terminals and stick them in. :)
My amplifier is parasound a23 and Arcam Neo Solo.
