Quick Overview

The Grado Reference Master uses Grado's specially designed nude elliptical diamond and features a Mahogany wood body with a fixed coil design. The 47 parts of each Reference cartridge are bonded together, creating a cartridge with a single resonance point. With just one resonance point to control, Grado is able to precisely control their desired frequency response. This is state-of-the-art in moving magnet design.


  • Grado-Master

The Master model uses a five piece OTL cantilever technology, achieving an additional 5% tip mass reduction over the Platinum and Sonata models. Reducing tip mass creates a cartridge with faster response, much like a high-end moving coil. The coils are wound with ultra-high purity long crystal (UHPLC) oxygen free copper wire.
