The Grado family is proud to announce a major step forward in phono cartridge design with the Grado Epoch, the flagship cartridge of the all-new Lineage Series. For the first time in the our sixty-four year history, sapphire, gold, diamond, and cocobolo wood join forces to produce the finest hand-built cartridge ever. The Epoch and Aeon, which see final assembly by John Grado himself on his workbench in Brooklyn, are two cartridges that offer exceptional reproduction of vocals and instruments, with superlative tonal balance, dynamics, imaging, and realism. Grado’s coil winding techniques, which have been honed throughout the decades, have let them achieve exact unison between the four coils in each phono cartridge. This allows for a precise balance between channels and accurate stereo imaging. Each Grado is wound with the finest properly sized and annealed 24-karat solid gold wire, which is the ultimate conductor for the transmission of the music from your record.
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. 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 Epoch and Aeon feature a unique system that has the lowest effective moving mass of any cartridge, while Grado’s patented Flux-Bridger generator design creates a superior balance throughout the full frequency spectrum with superb resolution and clarity, which produces an overall truer picture of the music. This is all nestled inside a cocobolo wooden housing.
In 1953, our family started building cartridges on their kitchen table. Every experience in our history has led to the creation of the Lineage Series. The Epoch and Aeon represent the craftsmanship and unwavering dedication to sound that has been Grado’s main focus for over half a century.
