Thank you all for your advice. I think I’m still inclined towards an Audio Technica AT-1100 though as I am in the UK the SME Series 3 will be easier to source. My thinking is that with the Audio Technica I can easily swap out the arm for the heavier AT-1010 using the same base, etc should I need to. I should probably have said my turntable is a Garrard 401 so the plinth can easily accept different armboards.
