The Master2 and Reference2 models use a five piece OTL cantilever technology achieving an additional 5% tip mass reduction over the Platinum2 and Sonata2 models. The coils are wound with ultra-high purity long crystal (UHPLC) oxygen free copper wire. The Master2 model is mounted with Grado's specially designed nude elliptical diamond, and the Reference1 model uses Grado's true ellipsoid design diamond. These cartridges are individually calibrated.
Each individual cartridge manufactured by Grado is hand assembled and tested for frequency response, channel output, channel balance, phase linearity, inductance and resistance. This meticulous care in design and construction lavished on each Grado cartridge contributes to an unchallenged consistency of performance and guarantee of reliability.
