All Grado cartridges use a derivation of the moving iron principle which features patented optimized transmission line cantilever technology, pivoted fixed axial stylus-generator module, and Grado's flux-bridger generator system.
The Prestige series of cartridges are designed for high output and excellent stability under severe use. A considerable tip mass reduction results in a frequency response to 50 kHz and beyond and tracking forces from 1-2 grams. Acclaimed by experts as virtually the finest pickups in the world at their price. Prestige models available in both 1/2" mount and P-mount. All styli in the Prestige series are user replaceable.
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.
