Auris tonearm upgrade for Sota Moonbeam?

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 have owned 6 OL arms including my current Enterprise and Conqueror on an OL table.  I started with OL many years ago with an original Silver.  I have mounted many cartridges on each of the arms without any issue of a broken wire.  Yes they are delicate but that does not mean the have a flaw from their construction.

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. ​​​​​​
