How is the Green2 different from the Prestige Black2 cartridge? It's simple. The Green2 cartridges are hand selected from Black2 production runs which meet higher test specifications.
The Green2 uses a three piece OTL cantilever that has a Grado specific diamond mounted on a brass bushing.
Grado’s OTL, or optimized transmission line, technology provides an ideal transfer of signal from the surface of the LP to the generator of the system. This technology rejects unwanted resonances and lowers distortion preserving the fundamental and harmonic frequencies of the music. This also helps keep noise generated by the motor system in the cartridge to a minimum. Grado’s OTL stylus/cantilever design makes records sound quieter, improves the height, width, and depth of the soundstage, and present more detail than previously obtainable.
All Grado phono cartridges are powered by a twin magnet system that optimizes the balance between stereo channels. All internal magnetic circuit parts are held to extremely high tolerances creating the desired stereo imaging. Grado’s patented Flux-Bridger design allows the Green2 to have one of the lowest effective moving mass generating systems while creating an excellent balance throughout the full frequency range.
