Into the Woods
The Sonata3 does everything the Platinum3 can do - but does it better thanks to an intricate processes while being crafted.
Everything you can do...
A Step Up
While
similar to its younger sibling in a few aspects, the Sonata3 has a much
longer build time since it undergoes extremely unique processes only a
few of our cartridges go through. This longer, more intricate practice
produces a more colorful and deeper sound.
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™. We modified our four piece OTL cantilever technology to
achieve a 10% tip mass reduction over the Prestige Series and use
ultra-high purity long crystal (UHPLC) oxygen free copper wire in the
coils. The Sonata3 uses a specially Grado designed nude elliptical
diamond.
The Sound of Wood.
Built from Jarrah
After
the Sonata3 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
Sonata3 is hand-built by our team in Brooklyn, as it has been for
decades. After a specialized process that brings it to life, 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
Sonata3 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 Sonata3.
