Hand-built in Brooklyn, the Sonata3 is 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. Grado's Sonata3 is made using a new 2 step shielding process to bring the exact unison between the four coils and unobstructed path for a cleaner signal. Undergoing a longer build time, results in a more colourful and deeper sound. 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.
To make the Timber 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.
