Thanks and I agree -- I did pull the trigger and order the Rega SS shim. I was just wondering if a wedge shim between the cartridge and tonearm to realign the angle was a preferred solution to adding a shim between the plinth and tonearm. Especially since Rega is silent on recommending the shim for the R3000 Tonearm.
... I'm sure I'm just overthinking it. They are probably just being silent on a shim for the P10 to encourage sales of their higher end cartridges.
