Sussurro MkII and surface noise?

If you ever do consult Peter Ledermann regarding your issue with the Sussuro please let us know what he says. He was very helpful to me when I had an issue with a Grace Ruby re-tip. And no one knows the sussuro better than he.

Peter's OCL is without question, and by far, the most difficult stylus profile to dial in with respect to overall setup that I've ever had to deal with. Extremely sensitive to VTA in particular with respect to how noisy it will be in the groove but also VTF and azimuth of course.

There will be a very narrow window with respect to VTA/SRA in terms of how it will perform with respect to not exaggerating groove/surface noise once it has broken in. It will be interesting to see if that setting conforms to what the AM software is telling you.

I'd agree with other posters about putting 50-60 hours on the cartridge before really getting serious on the setup. IMO, once you have azimuth set up properly you will then need to experiment with very small incremental changes in VTA/SRA along with similarly small changes in VTF at the same time (I'd be inclined to going higher into the recommended range of VTF than lower) to try and nail the setting.

You will know it when you hear it and it will be much easier for you if your arm has VTA on the fly adjustment (mine does not).

But virtually any other line contact stylus (including Peter's on his mid level retip) is much easier and more forgiving to set up. Any of the microridge styli are even more forgiving IMO.

Ditto for me with my Grace Ruby re-tip, using the OCL stylus.  When it's good, it's very very good.  Etc.

I sure don't have the experience that some here do but I found my Sussurro the easiest cartridge I've ever owned to set-up. Maybe I just got lucky?
