In relation to Styli type or form being solely influential on the produced sound. My own experiences have discovered the Styli does create change, but not enough to be considered as the the part that voices the Cartridge.
It is the materials selected to produce the Cart’ and the overall assembly method selected that is the voice of the Cart.
Many Cart’s come as a range of models, of which a range can all be closely related in materials selected, but a different Damper, Cantilever or Body Metal or Magnet, creates a change to the voicing that is quite detectable.
I assume tie wire tensioning or wire type, will also be a influence as well.
My comparisons of Styli Types alone, where differing types are used on very similar Cart Designs, where the Cart' is mounted on same Head Shell Material and used on the same TT and System, undoubtedly suggest detail retrieval and surface noise are where these Styli offer the least/most influence.
