An Achievement.
First of its Kind
When
it comes to the Opus3, there are a few “firsts”. This is the first
cartridge built with a maple wood housing, as well as the first to use
what we learned with our high-end cartridges at such an entry-level
price. The housing is a new shape but still keeps the wood working in
tandem with the cartridge inside. This is also the first cartridge built
specifically with the Timbre Series in mind.
The Sound of Wood.
Built from Maple
The
Opus3 is nestled inside a maple housing, something a cartridge has
never done before. After years of working with maple from our Heritage
and Statement Series headphones, we knew it was time to bring it to a
turntable. Maple produces a vibrant and luscious sound, while staying
consistent and clear. 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. 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.

Hand-Built in Brooklyn
Each
Opus3 is hand-built by our team in Brooklyn. Fine tuned for everything
from entry-level turntables up to the highest-end stereo systems, the
solid mass of the wood helps keep the Opus3 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
Opus3.
