Grado Blue2 Phono Cartridge
Awesome Sound in Red States and Blue StatesBoth 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.
Blue and RedThe 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. 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, 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 Red2 & Blue2 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 Red2 & Blue2 to have one of the lowest effective moving mass generating systems while creating an excellent balance throughout the full frequency range.

Nice Cartridge, Hums with Project Debut
I bought this cartridge as an upgrade over the Ortofon Om5e that came with my Project Debut III. It was an improvement especially in the midrange. The Grado was smooth as silk. The upper frequencies were vieled but I didn't get a chance to break it in due to the dreaded "Grado Hum" that occurs with some turntables. I had to swap it for an Ortofon 2M Red, which didn't hum. I regret not buying it from ND. I have a new TT now, so I may try it again and will buy from ND.
