Yes the binding posts come equipped with a jumper. You could replace this, but I would save your money.

You can reterminate with a correct size spade terminal, or you can buy banana's that have the ability to accept the spades. You could spend time "altering the size" of the current spades, but this could be somewhat less than satisfying. You could damage the spade, or create a connection that is not mechanically or electrically secure. Connections can alter sound, typically a bad connection can cause audible problems.
