Perhaps you were referring only to the cartridges mentioned in your post
and I don't know the composition of the cantilevers in the cartridges
mentioned. However, cantilevers are made from a number of materials
(Aluminum, Boron & Ruby, to name a few) and the designs are as varied as
the materials used. Some are solid, some are hollow and tubular and some
are hollow and tapered. So, the resonance will vary with the design.
And,there are other factors involved as well: Tracking force, Dampening,
even the electrical resistance (Termination), etc.
It certainly is a jungle out there, isn't it,
PS: Another problem with vinyl is the composition of the vinyl itself.
