The Grado Blue 3 is proof that you don't have to spend big money on a good-sounding phono stage.
The Grado OTL stylus/console makes the sound quieter, improves the height, width and depth of the soundstage, and provides more detail than previously possible.
Grado Blue 3s are hand-built by a team in Brooklyn, and some builders have over 25 years of experience. Thanks to the recent development of the highly acclaimed Lineage series cartridges, we have been able to bring new technologies and new techniques to the Blue 3. This updated series of cartridges offers superior tonal balance, dynamics and realism for the best reproduction of vocals and instruments. Coil winding techniques using ultra-high purity copper wire, which were honed during the development of the Lineage series, allowed the circuitry to achieve unison between the four coils in each phono stage. This ensures a precise balance between channels and an accurate stereo image.
Like all Grado phono cartridges, the Blue 3 is powered by a dual magnet system that optimizes the balance between the stereo channels. All internal parts of the magnetic circuit are maintained to very high tolerances, producing the desired stereo image. Grado's patented Flux-Bridger design allows the Blue 3 to have one of the most inefficient moving mass generation systems while maintaining excellent balance across the entire frequency range.
Epoch's development in the Lineage series has given a comprehensive experience of using the outer case as a damping device. This resulted in a process that takes the load off the chassis and dissipates unwanted energy and resonant frequencies, allowing the desired signal to propagate freely.
