Grado Labs Prestige Series Gold 1 Stylus
The Prestige (and upscale Reference) cartridges from Grado are the first released since the elder Grado's retirement, but they mark an evolution, not dramatic change, of the classic Grado style. There are three basic levels in the Prestige lineup: Black/Green, Blue/Red, and Silver/Gold. In each of these pairings, the latter model is the same as the former, but is able to meet more astringent test specifications. The Green, for instance, is taken from the top 15% of the Black models production.
The newly redesigned Silver1 and Gold1 have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. The Silver1 and gold1 models use a four piece OTL cantilever technology, ultra-high purity long crystal (UHPLC) oxygen free copper wire in the coils and Grado's specially designed elliptical diamond mounted on a brass bushing. The Gold1 model is selected from the Silver1 production run and meets higher test specifications. Approximately 5% of the production run meet these standards and become Gold1 models.
