The Red4 Grado Turntable T4P Cartridge

.:Right in the middle of the Grado Prestige 4 Turntable Cartridge Series:.

In addition to all the great features of the Red3 and prior generations, in Gen 4 you get an upgraded signal path that utilizes ultra-pure 5N OCC copper, chosen for its exceptional conductivity and reliability. Plus, every cartridge is cryogenically treated and continues to exclusively feature internal damping to minimize resonance and maintain pristine signal quality. This ensures a sound that is cohesive, well-balanced, and highly dynamic.



"The newly produced Alnico magnets are more powerful and also slightly smaller, but heavier. This change lowers overall distortion, reduces output a tiny bit, widens separation, increases dynamics, widens signal to noise ratio, and reduces phase/stray ambiance distortion. Clarity is increased rather dramatically from front-to-rear sound stage"......Robert H. Levi

From GradoLabs:
Both the Blue3 and Red3 use a four piece OTL cantilever that has a Grado specific diamond mounted on a brass bushing. The Red3 are hand selected from Blue3 production runs which meet higher test specifications. Approximately 10% of the run usually exhibits these specs and become a Red3.

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.

The Red3 & Blue3 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 Red3 & Blue3. 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 Red3 & Blue3 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 Red3 & Blue3 to have one of the lowest effective moving mass generating systems while creating an Excellent balance throughout the full frequency range.
