Grado Reference Platinum 1 Platinum1 phono cartridge 5.0mV
The newly redesigned Grado Platinum 1 cartridge offers four improvements over its predecessor. The coil design has been reconfigured. The size of the coils were reduced, cutting back on the number of turns, for improved sound quality. Grado Labs has developed a new process of potting the coils which helps control internal resonance in the coils which then lowers the noise floor even more than before. Also, the effective moving mass of their generating system has been reduced by 17%, thus allowing for a quicker and more accurate reproduction of music. All this is hand-assembled within a machined, new processed, Australian Jarrah wood housing. The wood enclosure has been changed from Mahogany to Australian Jarrah, which is a much harder and denser, thus adding greater stability to the cartridge as a generating device.
