Usually tonearms is rigidily coupled to either the top plate or plinth if you can't fully decouple them. No for me I have to rigidily couple to the top plate (my least favourite option) but beggars can't be choosers. My plinth is too small to directly couple to the tonearm so it has to be the top plate. There is more method to my madness with this coupling because I've used EVA which should mitigate some vibration getting into the tonearm. My Alphason is made for Titanium so is pretty stiff but I wonder if my M55E would benefit from another layer of vibration protection with my Mpingo would spacer? In an ideal world you wouldn't have so many interfacing surfaces as this is bad for vibration supression/control but again beggards can't be choosers and I'll look into this when I get the new plinth. :eyebrows: I'm pleased to annouce that I've finally got the 2mm vinyl clearence that I wanted from the base of cartridge to vinyl's playing surface. The tonearm is now rigidily coupled to the top plate and is correctly set up with regards tonearm geometry, tracking force, etc etc so I can now relax when listening to vinyl in the knowledge I've done all I can with the tonearm. I also took this oppotunity to make sure that everything was as tight as possible when rebuilding the '75, nuts and wing nuts got the full mole-grip treatment.
