Ships to US only

The Grado Reference Master 1 Phono cartridge is a fixed coil design, handcrafted at Grado Labs from specially selected species of mahogany. Unlike the Grado Prestige series, the Grado Reference cartridges have a generator/stylus module that is not replaceable thus allowing a redesigned one-piece magnetic circuit and a reduction of chassis resonances. The Grado Reference phono cartridges utilize manufacturing and assembly techniques of superlative accuracy and precision. The result is virtual perfection - the finest phono cartridges in the world! To hear the celestial performance of the Grado Reference cartridges, we recommend that they be used with the finest equipment.

The Grado Reference Master 1 phono cartridge features a specially designed nude elliptical diamond mounted on a brass bushing and a modified five-piece OTL cantilever technology achieving an additional 5% tip mass reduction over the Grado Reference Platinum and Grado Reference Sonata cartridges. The coils are wound with ultra-high purity long crystal oxygen free copper wire.
