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?

Oops, never mind.  I just found the specs for my Moonbeam have 222 mm from spindle to armhole mount, while the Auris is 211 mm according to this.

Yeah I'm thinking about an Origin Silver now, thanks for the ideas.  They say they are drop-in replacements for all Rega arms.

Yes I saw that; I would consider the screw holes to be an appropriate indicator of the upgrade, so probably wouldn't cover them up.

Can you tell me how the cartridge gets connected to the Origin arm?  The Rega/Sota arm has the tiny brass clips soldered on the ends of the wiring, and I was reading the Origin website material about the importance of connections and not using brass etc.  Also those solder joints are extremely hard on the wires and they tend to break every time a cartridge is removed and replaced.

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.
