Cartridge Setup Question for Rega P10 with Hana Blue

I have an ML on a p8. Adding the 2 piece 2 mm shim was painless and made a world of difference in the SQ.  Much more detail yet smoother. Highly recommended.  

This thread convinced  me to definitely use a shim.  I ordered both the Rega SS shim and the acoustic signature shims... Will take a look at differences.  I'm not sure if one piece shim is preferred over stacked shims, but ithe difference is probably negligible if the screws are torqued tightened correctly.

I just wish Rega wasn't silent on shims for the P10 tonearm..

@mikei I once did the same upgrade and found that no shim was needed.

Yes, there is a difference in cart height, but if you run geometrical calculations given the difference in height and the length of the Rega tonearm, you’ll find that the change in VTA is less than the typical manufacturing tolerances for the cantilever angle.

So...I wouldn’t worry about it.

Investing in the Rega P10 WITHOUT the Aphelion/AphetA goes against the Rega philosophy.

What's simpler than 3 mounting bolts, adjust tracking spec/AS-done?

Is the Hana "better" to the ears than either Rega cart which both get positive reviews?

Hopefully, you have a phonostage at the Rega P10 level to enjoy it's potential.

Thanks. I'm sure your right....  Ha, I think trying to optimize the setup is probably more about having fun than expecting significant improvements. I'm still new to this hobby, so I have a lot to learn.

Now, I need to learn a little more about the calculations you mentioned.
