I am sure this applies to the RP8 as well. But I have an RP10 and bought two of the 2mm shims to accommodate the VTA of a Kleos cartridge. My dilemma is that the single shim does tighten the bass to where i prefer but the highs and mids drift from what I prefer. With both shims the highs and mids are, in my opinion, exactly what I want, but the bass control starts to slip away. Does any one know of a 3mm shim? I think that would bring everything into line. I will experiment with tracking force, but am reluctant to drift to far from 1.75 which was ideal on my old LP12. I looked at Acoustic Signature but this are drilled for the RP6 which uses a smaller screw. Also I am considering the Groove Tracer counterweight, but I really don't see that as the correct solution for this issue, but rather a tweak once the VTA is corrected. So my question is, anyone have an RP8 or 10 that has come across this issue and have you found a different supplier of shims for the Rega. I have thought about filing my extra 2mm down but realize I cannot maintain a perfectly flat surface.
Try adding a mat? Even making a paper mat or mats to adjust the height difference to lock it in. Then you could either look for the exact shim, or have one of your shims cut down to the exact thickness by a machine shop. Or you might even like the mat.
