Seems like the Origin Live tonearms will fit with the Rega mounting plates. I’ve decided that sometime here in the near future, I’m going to replace my Thorens tonearm with the Onyx. I would opt for the Silver but with a dedicated mono cartridge, it probably won’t matter that much. Anyhow, the Onyx is about $600,00 and according to what I’ve been reading, out performs many arms twice it’s price.
So I’m assuming that I’m correct in saying that an OL tonearm would be an easy install with any Rega table and they are offer a wide range. So matching the arm model with the plinth and cartridge quality would make OL a viable option.
