Grado Labs Prestige 1 Series Green1 Phono Cartridge

Grado Labs

The newly redesigned Black1 and Green1 have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. 

  • The Black1 and Green1 models use a three piece OTL cantilever technology, standard oxygen free wire in the coils and Grado's specially designed elliptical diamond mounted in a brass bushing. The Green1 model is selected from the Black1 production run and meets higher test specifications. Approximately 15% of the production run will meet these standards and become Green1 models.
