Dear @robbiesd: You own one of the best tonearm designs ever, way superior to any unipivot one. It's a very well damped design with great bearing design.

You can't be sure about that 7hz resonance frequency especially if you measured through those imperfect LP tracking tests.

As you said you are satisfied with the quality level performance with no problems at all that can been caused by that theorical 7hz resonance fr.. It's almost impossible that that 7hz theretical resonance can be precesily mated/even during playback coming from some anomalies in that playing proccess.

Even you can improve the quality sound performance level you have doing a internal re-wirin in the tonearm and with better headshell wires on what you are using in the headshell.

The EPA-100 is a very good design too and you can try with the Grace but in both tonearms the re-wiring is a must to do as the headshell wires.

No, I don't think that you need a different tonearm when you already own two of the best ever.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Robbie, No problem about misspelling my moniker.

Robbie,

Thanks for the RS-9E.  Looks great and will mount it and the 9-F soon. I think it will work best on my Audiomods Series V.
