Because of the integrated nature of the design replacement styli cannot be purchased for this cartridge, they must be factory replaced.
The newly redesigned Signature has its coil design reconfigured, and the effective moving mass of its generating system has been reduced by 17%. All this is hand-assembled within a machined, new processed, ABS housing
