Replicant 100 is the description used by Ortofon for their highest level stylus. In the techno babble accompanying the models equipped with Replicant 100 is says this was designed in collaboration with Gyger, suggesting Ortofon had a hand in the final shape. The same is said about the very similar Ortoline stylus used in MC 7500. This a probably why the name Replicant 100 is used exclusively by Ortofon, although it was made by Gyger. Usually such an arrangement excludes the maker to supply this stylus to other brands. Yet I have a first edition Benz LP that has the exact same stylus/cantilever as Ortofon A90, A95 and Anna. It seems likely that Gyger supplied it to Benz, but it was not called Replicant 100. The later LP (with the bronze body parts) used a micro ridge. The stylus change was of course described as an improvement, but perhaps this also had contractual reasons.
This provides no answer to who’s making this stylus now, since Gyger is said to be out of business, but I have low knowledge levels 😁
