Grado cartridge models Silver3 and Gold3 from Prestige 3 series.  Cartridge features a four piece OTL cantilever with a Grado specific elliptical diamond stylus mounted on a brass bushing. It brings a lower distortion and greater transparency. The OTL technology rejects unwanted resonances preserving the harmonic frequencies  and brings an absolutely detailed music. The Silver3 and Gold3 models are powered by a twin magnet system that optimizes the balance between stereo channels.
