All Reference Series2 cartridges offer a low mass generating system, and a diamond cut specially for Grado. In addition the Reference2 and Master2 are installed with a boron cantilever. The output for the Reference Series2 measures at 5 mV. The frequency information and its portrayal of bass dynamics are solid, powerful and authoritative. The midrange is rich, complex and highly believable. Its top-end seems to extend forever with speed and remarkable delicacy. Imaging is detailed and precise with a sound stage that wraps its arms around you and draws you into the music.
The Platinum2 and Sonata2 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 Platinum2 model uses Grado's specially designed elliptical diamond mounted on a brass bushing, and the Sonata2 model uses Grado's specially designed nude elliptical diamond.
