GRADO phono cartridge
Timbre Master3 (Stereo, High)

This product is ordered from a distributor. Please allow 2-3 business days from order for dispatch.

Master3, like the Reference3, is made of Australian Jarrah wood that has undergone a proprietary treatment to increase its hardness. This process suppresses resonance and optimizes the housing to a high degree of precision, providing superior sound as the cornerstone of the Timbre series. A solid elliptical needle made of synthetic diamond is mounted on a 5-piece OTL cantilever with a mass reduction of 5% compared to the Prestige series. The coils are made of high-purity UHPLC (Ultra high purity long crystal) oxygen-free copper, a luxurious specification that is close to that of higher-end models.

This is a stereo high output model.


Product Features


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.

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.

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 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.
