Auris tonearm upgrade for Sota Moonbeam?

The Origin Live tonearms have the same mounting distance as Rega.

222mm+/-2mm is a pretty popular P2S distance for nominal 9-inch tonearms, so there are probably many that would fit with a little finagling.

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

I have an OL Silver 3a on my Basis, the only rub is the OL arms mount with a central pillar and bolt, exactly like the older Rega arms. If your arm has the modern 3 screw base, OL makes a very inexpensive vanity plate that will cover those screw holes.

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.
