I am not really sure, but I think, the Ruby 3 has a shorter Cantilever ( or needle?). Anyway, the Benz Systems are good to listen to. I prefer them more than others, but they all have one in common: I always 'rated' my records with them ( ... good sounding, nice voice, audiophile grade etc. ).
I changed to different systems.
But listening to Voices, it's a class of it's own, no doubt.
