GRADO BLACK3 (BLACK 3) PHONO CARTRIDGE
Grado cartridges are acclaimed worldwide by experts as virtually the finest pickups at their price points. The Grado Prestige series of cartridges are designed for high output and excellent stability under the most demanding conditions. All of the range uses Grado's patented Optimized Transmission Line (OTL) technology which makes your records sound quieter, improve the height, width and depth of the sound stage and offer more detail than previously achievable. Grado's OTL technology is all about delivering more music, more performance.
The Black3 uses a three-piece OTL cantilever that has a Grado specific ellptical diamond mounted on a brass
bushing. Grado’s optimized transmission line (OTL) 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.
Black3 cartridges are all hand-assembled by Grado artisans in Brooklyn, with some builders having over 25 years of
experience. With the recent development of the highly received Lineage Series of cartridges, Grado was able to take advantage of
its trickle technology and bring a new technique to the Black3. This updated series of cartridges offer excellent
tonal balance, dynamics, and realism, for a most rewarding reproduction of vocals and instruments. Grado's coil winding techniques,
using ultra high purity copper wire which were honed during the development of the Lineage Series, lets 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 Black3 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 Black3 to have one of the lowest
effective moving mass generating systems while creating an excellent balance throughout the full frequency
The development of the Epoch in the Lineage Series gave Grado an in-depth experience with using an outer
housing as a damping device. This led to the creation of a process that de-stresses the chassis and
dissipates unwanted energy & resonant frequencies, allowing the desired signal to travel with purity.
