Grado Labs Blue2

As in all Grado phono cartridges the Grado Labs Red2 & Blue2 are powered by a twin magnet system.  As a result we can optimize the balance between stereo channels. We hold all magnetic circuit parts to extremely high tolerances.  This creates the desired stereo imaging. Grado’s Flux-Bridger allows the Red2 & Blue2 to have one of the lowest effective moving mass generating systems. Of course the result is an excellent balance across the full frequency range.

Description

As in all Grado phono cartridges the Grado Labs Red2 & Blue2 are powered by a twin magnet system.  As a result we can optimize the balance between stereo channels. We hold all magnetic circuit parts to extremely high tolerances.  This creates the desired stereo imaging. Grado’s Flux-Bridger allows the Red2 & Blue2 to have one of the lowest effective moving mass generating systems. Of course the result is an excellent balance across the full frequency range.

Making the Epoch in the Lineage Series gave us an in-depth experience with using an outer housing as a damping device. This led to the creation of a process which de-stresses the chassis. Therefore, this dissipates unwanted energy & resonant frequencies. Which allows the desired signal to travel freely.

<h4>Grado OTL</h4>

Both the Blue2 and Red2 use a four piece OTL cantilever that has a Grado specific diamond mounted on a brass bushing. The Red2 are hand selected from Blue2 production runs which meet higher test specifications. Approximately 10% of the run usually exhibits these specs and become a Red2.

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.

<h4>Made in the USA</h4>

The Red2 & Blue2 are all hand assembled by our team in Brooklyn, with some builders having over 25 years of experience. With the recent development of the highly received Lineage Series of cartridges, we were able to have a trickle down of technology and bring a new technique to the Red2 & Blue2.

As a result, this updated series of cartridges offers excellent tonal balance, dynamics, and realism, for a most rewarding reproduction of vocals and instruments. Our coil winding techniques, which use ultra high purity copper wire 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.
