A major step forward in phono cartridge design, the sapphire, diamond, and cocobolo work in harmony to bring this cartridge to life. The specially designed diamond stylus, for the first time in a Grado, is mounted on a sapphire cantilever that connects to the stylus generating system. The Aeon features a unique system that has the lowest effective moving mass of any cartridge, staying steady on your turntable.
In the Details.
All of the internal magnetic circuit parts are Swiss screw machined or molded metal, which have tolerances on the order of the best Swiss-made watches. Grado’s coil winding techniques, honed throughout the decades, bring exact unison between the four coils in each phono cartridge. This creates precise balance between channels and accurate stereo imaging.
The Sound of Wood.
Built from Cocobolo
The flagship Grado cartridge is nestled inside a cocobolo housing, adding solid mass and a bold yet revealing signature sound. Cocobolo, known for fine instruments and those chess sets that look too nice to touch, is some of the most beautiful and tonally pleasing woods we have ever used. Its denseness and grain is a primary reason why it produces such a unique sound.
Hand-Built in Brooklyn
Each Aeon built sees final assembly by John Grado himself on his workbench. Every experience in our history has led to the creation of the Lineage Series. The Aeon represents the craftsmanship and unwavering dedication to sound that has been Grado’s main focus for over half a century.
