Grado Prestige Series Blue1 Turntable Phono Cartridge for Record Players
Grado Prestige Series Blue1
Turntable Phono Cartridge
The Prestige series of cartridges are designed for high output and excellent stability under severe use. A considerable tip mass reduction results in a frequency response to 50 kHz and beyond, and tracking forces from 1-2 grams. Grado's Prestige Series cartridges are acclaimed by experts as virtually the finest pickups in the world at their price.
Grado's redesigned Blue1 phono cartridges have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. The Blue1 uses a four-piece OTL (optimized transmission line) cantilever technology, standard oxygen free wire in the coils, and Grado's specially designed elliptical diamond mounted in a brass bushing.
Each Grado Blue1 phono cartridge is hand-made in Brooklyn, New York and tested for frequency response, channel balance, phase linearity, inductance, and resistance. All Blue1 cartridges feature user-replaceable stylii.
