The Nordost Z-plug is a very fine connector. I like it better than spades because it does not require tightening of the binding nut and it offers a very large contact area.
For all, do not confuse the Nordost Z-plug with and ordinary banana. An ordinary banana has limited surface contact area. The Z-plug has contact over the complete other surface as it is made of "spring" metal and expands in all directions to make complete contact with the inner surface of the binding post.
Unlike spades, it does not require periodic tightening of the binding post.
Enjoy,
