Image: Ultralink PRO-BANANA. Milled copper, direct gold plate, compression type termination.The Edison Price Music Post offers a rather unique fit for banana plugs. The post is split, and when the nut is tightened the post can grip the banana pin with a high torque. The Eichmann's plastic pin will likely be crushed. Furthermore, using a locking-type banana is moot, and will only add more mass, and a typical beryllium spring leaf type is also not such a good idea, since the leaves will also likely be crushed and are pointless as used for a Edison Price Music Post's torqued fitting method.
A hollow pin type banana is ideal for the Edison Price Music Post. A spring-loaded hollow pin (non-split type) or a BFA banana would be perfect.
AudioQuest makes nice BFA bananas, and Ultralink makes a nice spring-loaded hollow pin type copper banana (see image).
A spring-loaded hollow pin type banana is perhaps the most suitable, since it is very solid (while still hollow) and would hold it's shape even better than a split-pin BFA banana would.
Follow Ups:
The Eichmann bananas crush or don't crush, it surely depends on how hard you tighten the post.
...but, if I were to go with bananas, I would like to use the Edison Price Music Post's potential for high torque, and the Eichmann's are limited in what they can handle in this regard. Also, the Eichmann's will not meet the Edison Price Music Post's conductive area unless positioned properly.
Image: "typical" binding post with shallow slot.A needed warning: The Ultralink PRO-BANANA has a crummy fit on a binding post that has a shallow banana slot. The PRO-BANANA's spring needs to have a deep well to do any good. If inserted in a shallow slot, the pin's grip is sissy if zilch.
...I tested the Ultralink PRO-BANANA on another lower cost 5-way binding post that "appeared" to also have a shallow slot (not so), and it gripped like a champ. So, my warning is dependant more on a specific binding post design, not a price-point issue.
I've used the AudioQuest BFA bananas on my last two pairs of speaker cables, and they are excellent. Very tight fit, and nice sonics.
Is the "pin" of the plug the actual part you crimp?
If you want to go with a reusable BFA banana, I think this is a good choice...AudioQuest CFG Bananas:

That's what I'm looking for, something that can be reused.
Duster,
Is this an XLO product, where can it be purchased?
Ultralink is XLO's parent company. Their connectors are made in-house in Canada (maybe some in USA) so they aren't cheap off-shore stuff.One thing to note is that this type of compression-fit connector is best suited for fine strand, stranded conductors (high strand count). It is not as adept at terminating medium strand count stranded conductors or solid core wire with, as the connector's "nut" complains about the torque, and a firm-fitting is not the best (it likes a softer "push" to torque against).
However, since a similar hollow pin type banana has not been found in my research at least, it can be soldered with some finesse (it's a worthy choice for a tricky solder method, either to the main body or the "nut").
The other thing to note is; if the conductor is soldered to the connector's "nut", it will be in effect a modular termination, in that an Ultralink PRO-SPADE can be screwed onto the "nut" for a possible connector swap. While a modular connector is not optimum due to another surface connection, it can be a handy thing (such as MIT's modular "iconn" speaker connector system is).
Here's one source for the Ultralink PRO-BANANA (a set of four, I think):
