Grado Labs Prestige 1 Series Blue1 Phono Cartridge

Grado Labs

The newly redesigned Blue1 and Red1 have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. 

  • The Blue1 and Red1 models use a four piece OTL cantilever technology, standard oxygen free wire in the coils and Grado's specially designed elliptical diamond mounted on a brass bushing. The Red1 model is selected from the Blue1 production run and meets higher test specifications. Approximately 10% of the production run will meet these standards and become Red1 models.

    • Reduced moving mass by 17%
    • Four piece cantilever technology
    • Approximately 10% of production run will be deemed worthy of being labelled Red1 models
