I have the same type on my Marantz integrated and I really don't like them. They're touted as top flight 5 way binding posts but they really limit the way one can hook up speaker wire. Bananas are the easiest, followed by bare wire (but it's so much easier threading from above than bellow, which can be very frustrating) and as for spades, you can only insert them from above.
If you are installing them yourself, make sure you orient them the way you like, if possible.
Mine can accommodate 1/2" spades but not all spades are equal. Any deviation from straight on either side of the tine can snag. I had a Dickens of a time trying to get an older pair of spade ended wires to connect. Some ends went in okay but others didn't.
All the best,
