Rega RP10 VTA shims


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.

I have observed that the Rega Tonearm + Rega cartridge have a positive VTA (a pivot end raised slightly ) . So, we can not consider only the cartridge height to determine how many shims we should use to adjust the VTA in a Rega Turntable when using a cartridge from other brand. It will vary from cartridge to cartridge. Actually, the measure we should be worried about is the SRA. Much more important than the VTA which at the end is one of the ways we will utilize to try to achieve the optimum SRA adjustment.
