Grado - Prestige Series - Blue3 Turntable Phono Cartridge

The Grado Prestige Blue3 Turntable Phone Cartridge delivers pure sound from your turntable. Attach it to your tone arm and get high-powered sound. Its unique four-piece OTL cantilever technology makes your records sound quieter, improving the height, width, and depth of the soundstage. All four pieces are made of different materials, to offer more sound detail than previously obtainable.

Grado has redesigned the Blue3 and Red3 cartridges. Their coil design has been reconfigured, and the effective moving mass of their generating system has been reduced by 17%. The Blue3 cartridges use a four piece OTL cantilever technology, standard oxygen free wire in the coils and Grado's specially designed elliptical 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.

The Blue3 is hand assembled by Grado's team in Brooklyn, NY, with some builders having over 25 years of experience, including John Grado himself. This updated series of cartridges offers excellent tonal balance, dynamics, and realism, for a most rewarding reproduction of vocals and instruments. The coil winding techniques using ultra high purity copper wire, which were honed during the development of the Lineage Series, have let the electrical circuits achieve unison between the four coils in each phono cartridge. This allows for a precise balance between channels and accurate stereo imaging.

As in all Grado phono cartridges the Blue3 is 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 Blue3 to have one of the lowest effective moving mass generating systems while creating an excellent balance throughout the full frequency range.

Note: The Blue3 cartridge is the direct replacement for the older Grado ZF3 cartridge.
