Grado Reference Master 1

Grado Reference Sonata 1 platenspeler element

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.
