Cured Jarrah For The Cure
Nearing
the top of the Timbre Series, the Master3 achieves optimal sonic
quality due to an intricate curing process and specialized materials
reserved for our best cartridges.
From Here on Out.
On Reserve.
Some
practices we reserve for cartridges near the top of the line, and it
starts here. To achieve our desired sound, we experimented with multiple
longer curing processes that differ from the Opus3, Platinum3, and
Sonata3 while using more modified materials. Each Master3 is
individually calibrated after being built.
Small Necessities.
The Materials
To
make the Timbre Series work as a whole, we created a way for Jarrah,
diamonds, and a twin magnet system to integrate with our Flux-Bridge™.
Unlike the cartridges before it, we modified our five piece OTL
cantilever technology to achieve a 5% tip mass reduction over the
Prestige Series and use ultra-high purity long crystal (UHPLC) oxygen
free copper wire in the coils. The Master3 uses a specially Grado
designed nude elliptical diamond.
The Sound of Wood.
Built from Jarrah
After
the Platinum3 cartridge is crafted, it is then placed inside a
Australian Jarrah housing. Jarrah is necessary for the majority of
Timbre Series with its ability to produce surgically precise clarity
without losing any depth. Through a variation of thermal
aging processes, the housing gains the ability to better dampen and
control the resonant frequencies.
In the Details.
Extreme Precision
Grado
has combined newly developed coil winding techniques with decades-old
disciplines. A new two-step shielding process brings not only exact
unison between the four coils but an unobstructed path for a cleaner
signal. The music is allowed to travel undistorted through the coils,
greatly reducing mechanical noise while improving tracking. There is an
extreme clarity over the full frequency range, with absolutely no
stridency or shrillness. Precisely hand tipped with a diamond, a great
amount of care go into each cartridge we build.
With Love.
Hand-Built in Brooklyn
Each
Master3 is hand-built by our team in Brooklyn, as it has been for
decades. They are fine tuned for everything from entry-level turntables
up to the highest-end stereo systems, the solid mass of the wood helps
keep the Master3 steady and producing the Grado signature sound. We
started building cartridges on a kitchen table in 1953, and every
experience since then has led to the creation of the Master3.
