Pari al nuovo (usata poche ore per alcune Demo)



This MC Cartridge employs a push-pull electrical generating system based on a 2-magnet, 4-pole magnetic circuit design. Both in theory and practice, this revolutionary configuration almost entirely prevents the generation of any distortion, while simultaneously doubling output voltage.

Our coreless coil reduces effective mass and eliminates hysteresis distortion, a large problem with conventional MC cartridges that have their coils wound on a core made of permalloy or other magnetic materials. In our system there is no core, magnetic or otherwise, to prevent linear conversion of stylus/cantilever movement into an electronic signal.

The veryrigid, specially processed, aluminium alloy body and headshell are integrated to effectively prevent partial resonances.
