(https://www.ortofon.com/stylus-10-p-370) . The OM 20 is nude ellyptical ,lower mass,better than the 10
Both are superior ,hifi styluses. Don't know about the STY 10 , I assume it could be a third party replacement ? Most users say the originals Ortofon are way better .
I admit ,never heard a third party replacement ,the ProS or the Sty10 , so, can't judge them

No adjustments are able to be done besides tracking weight and AS, which I have set at 1.5. It's not awful, but barely noticible as some records near the end. Looking for an improvement there. Otherwise I like it a lot.
DeepEnd wrote:I think Rafael is correct the difference is more of a "refinement" than dramatic between the 10 and the 20. The 20 is slightly less prone to sibilance (particularly on female vocals), gives a slightly smoother tone on violins, gets less confused on complex classical recordings, gives a slightly more precise imagery and tracks slightly better.
These are the things that I would expect to continue to improve during the initial burn in period so you may find the differences sort of "sneak up on you" and it may be a while before they are fully apparent but once noticed it's hard to go back and not have them.
Yes the 30 is more of a jump in performance and I actually prefer this to the more expensive 40.
