Grado Timbre Reference3 Phono Cartridge Achieving fantastic accuracy and control, the Reference3 does everything the Master3 can do - but does it better thanks to specialized intricate processes while being crafted. Grado modified its five-piece OTL cantilever technology to achieve a 5% tip mass reduction over the Prestige Series. The Reference3 uses ultra-high purity long crystal (UHPLC) oxygen-free copper wire in the coils, and a Grado-designed nude elliptical diamond. Each Reference3 is hand-built by Grado's team in Brooklyn, as it has been for decades.
