Grado Labs Ref Series Sonata1 4.0mV Phono Cart Half Inch Mount

Grado Labs

The newly redesigned Platinum1 and Sonata1 have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. All this is hand-assembled within a machined, new processed, Australian Jarrah wood housing.

  • The Platinum1 and Sonata1 models use a modified four piece OTL cantilever technology achieving a 10% tip mass reduction over the Prestige series and ultra-high purity long crystal (UHPLC) oxygen free copper wire in the coils.

    The Platinum model uses Grado's specially designed elliptical diamond mounted on a brass bushing, and the Sonata model uses Grado's specially designed nude elliptical diamond.
