Auris tonearm upgrade for Sota Moonbeam?

The thing that puzzles me about the standard way to connect a cartridge, is that the cartridges themselves have four pins arrayed in a block.  This seems perfect to be mated to... I don't know... a plug?  Why do we have to connect individual wires to the four pins when a plug would make more sense?

I would suspect b/c of weight. ​​​​​​

Respectfully disagree, the reason for having four wires, rather than a single connector, is that there is no standard for the distance between the pins on a cartridge, and even more confounding, there is quite a variation in the diameter of the pins on various cartridges, which means that one needs to have a way to adjust the size of the hole in the connector. Some pins are even offset, in almost a diamond pattern, such as Shure and ADC, while others are in a square pattern. 

If I may make a suggestion, when you have the headshell wires disconnected, put a bit of Elmer’s white glue on a toothpick and put a generous drop of it right at the point where the connector is attached to each wire, and let it thoroughly dry. You will minimize the likelihood of breaking off the wires when reattaching them, or changing cartridges. Be sure not to use any adhesives that are reactive with metal or plastics.

Now some may argue that this will change the dialelectric properties of the insulator, but the benefits would, IMHO, outweigh any such concerns. Good luck.

I didn't realize that there was no standard configuration for the pins on cartridges, that's funny after all these years, to learn this.

The headshell wires from Sota have a small tip of bare wire which has been soldered to the clip, and the rest of the wire is insulated, so the tiny bit of fine wire really wants to break off from the solder since it is trapped there with no flexibility.  I see how some glue could help the situation.
