Machiavelli's extra rigid cantilever handles a high precision Line Contact diamond in the Gold model and a Micro Elliptical diamond in the Red model, both developed in collaboration with Adamant-Namiki, the world's most famous professional Diamond manufacturer. The diamond tip is mechanically inserted and blocked into the new cantilever that is consequently handled by a special pipe to increase the structure rigidity. The cantilever suspension takes advantage of an elastic and non-deformable harmonic steel spring, rigidly blocked to eliminate vibrations thus enhancing the tracking capability. With thin and long gold-plated pin connectors, Machiavelli is designed to connect perfectly with arm cinches, reducing energy dispersion and improving grounding for an ideal music background necessary to enjoy even the smaller details in your records. The Machiavelli Series feature high internal impedance high output levels and can be easily matched with any active phono preamp for MM/MC cartridges, without the need of Step-Up transformers. * all Machiavelli cartridges come with serial number indelibly printed in the engraved area at the top of the body Machiavelli Gold Machiavelli Gold offers extra rigidity with its Boron cantilever and 80 ohm high internal impedance and 1.2mV output level to easily match with MC and MM phono preamps set-up without Step-Up transformers.
