The Grado Blue1 and Red1 cartridges are upgraded versions of the originals. The effective mass of their generating system has been reduced by 17% and their coil design revised. These improvements provide improved tracking, transient speed and resolution. Out of the Blue1 production run, 10% of the units that meet the highest test specifications are chosen to become Red1.
The Blue1 and Red1 models use a four piece OTL cantilever technology.
