Grado Reference Master 1 Moving Iron Cartridge 

Handmade by skilled Grado engineers, the Grado Reference Master 1 moving iron cartridge has redesigned coils wound with UHPLC oxygen-free copper wire to reduce effective moving mass by 17%, which enables the Grado Reference Master 1 to track the most difficult inner band musical passages with ease at a tracking weight of just 1.5g.

With a body carved from Australian Jarrah wood for low resonance, has a 5 piece OTL cantilever which reduces tip mass by 5% over the Platinum 1 and Sonata 1 models. The sound quality is incredibly smooth and detailed, with a powerful, rhythmic bass, opaque, creamy midrange and superb three-dimensional stereo soundstage. The stylus is a high quality nude elliptical diamond, polished to perfection.
