What could be offered as a simplistic method ??, as a means to experience different Cantilever Styli assemblies would be on where the Joint Pipe projecting from the Armature, was a Threaded Stub.
A Cantilever that is commonly seen inserted into the Joint Pipe, can have an assembly where the Joint Pipe is internally threaded and pre-bonded into the Cantilever.
This would leave the connection of the Cantilever to the Armature as a method not needing adhesives, which should then have a set up where Cantilevers are at much less risk of being damaged when exchanging.
The idea of not using adhesives, will make a Cantilever exchange much more predictable and possibly more affordable, hence making the idea of experiencing differing C'lever>Styli forms a easier one to ponder.
A Third Party Service could quite easily produce a Cart' that enables for this to be part of the design, and could have a sales model in place that prior to purchase enables the buyer to have a option to experience different configurations, such as Styli Type, Cantilever Material, Connector Sleeve Material.
Everything I have learned about Cart's especially MC's, leaves me of the view the Styli form has the least overall impact on the sound being produced.
The most that influences the sound being produced in order, is the Magnetic System chosen, the Coil Wire Type, Damper Material Type and the overall structures function, as a result of materials chosen for the Cart's assembly.
All that I have experiences of, leaves me of the view, that if there was a Cart' with Cantilever Part, that had a bonded threaded sleeve as the coupling to Armature method. If this was able to be supplied in a variety of materials, there will be materials used that will show a noticeable difference to a sound being produced.
Or forget such ideas, maybe sticking with with what is a time served proven method, ' if it isn't broke why attempt to fix it . '
