As in all Grado phono cartridges the Red3 & Blue3 are powered by a
twin magnet system that optimizes the balance between stereo channels.
All internal magnetic circuit parts are held to extremely high
tolerances creating the desired stereo imaging. Grado’s patented
Flux-Bridger design allows the Red3 & Blue3 to have one of the
lowest effective moving mass generating systems while creating an
excellent balance throughout the full frequency range.
The development of the Epoch in the Lineage Series gave
us an in-depth experience with using an outer housing as a damping
device. This led to the creation of a process which de-stresses the
chassis and dissipates unwanted energy & resonant frequencies,
allowing the desired signal to travel freely.
