Grado Prestige Series Red1 Turntable Phono Cartridge / for Record Player's
Grado Prestige Series
Red1 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 Red1 phono cartridges have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. The Red1 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. Red1 phono cartridges are hand-selected Blue1 cartridges that meet stringent criteria. As such, only about 10% of the Blue1s are selected to become Red1s.
Each Grado Red1 phono cartridge is hand-made in Brooklyn, New York and tested for frequency response, channel balance, phase linearity, inductance, and resistance. All Red1 cartridges feature user-replaceable stylii.
