Unfortunately, the silver base cannot be added by the owner. It is permanently installed by Nakatsuka-san during assembly of the cartridge.

P.S. For fun, I've tried using external headshell weights with a ZYX. Bad idea. The sound, while weightier, went smeared and murky. It lost that astonishing clarity that makes a ZYX a ZYX.
