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.
Grado reserves some practices for cartridges near the top of the line, and it starts here. To achieve their desired sound, Grado 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, Grado created a way for Jarrah, diamonds, and a twin magnet system to integrate with our Flux-Bridge™. Unlike the cartridges before it, Grado modified their 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.
 
In the Details. - Extreme Precision
Combining newly developed coil winding techniques with decades-old disciplines, the four reconfigured coils find exact unison to create a precise balance between channels and true stereo imaging. A new four-step shielding process allows the isolation of the wire turns in the coils, and creates an unrivaled clear path for the signal to travel. The diamonds are cut to strict specifications to accurately ride the grooves on vinyl.
 
The Sound of Wood. - Built from Jarrah
After the Master3 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. 
 
With Love. - Hand-Built in Brooklyn
Each Master3 is hand-built by Grado's 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.
