Can 3 Way Binding Posts Accept Spades?????

Before spending more money on speaker cables, I want to know for sure if 3 way speaker binding posts can accept spade connectors. My speakers are KEF 103/4 (3 way binding posts) and I am currently using speaker cables with bananna plugs on them. Thanks.
Yes, bananas, spades, bare wire or pins ...
Thanks. Now that brings up another question: If that is the case, what is the difference between 3 way and 5 way binding posts?
2 of the 3ways go both ways. ;-)
