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.
To make the Timbre Series work as a whole, Grado created a way for Jarrah, diamonds, and a twin magnet system to integrate with their Flux-Bridge™. They modified their 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.
In the Details.
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 goes into each cartridge they build.
The Sound of Wood.
House of Jarrah
After the Sonata3 cartridge is crafted, it is then placed inside an 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 ageing processes, the housing gains the ability to better dampen and control the resonant frequencies.
Hand-Built in Brooklyn
Each Sonata3 is hand-built by Grado's team in Brooklyn, as it has been for decades. After a specialised 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. They started building cartridges on a kitchen table in 1953, and every experience since then has led to the creation of the Sonata3.
