Grado Lineage Aeon4 Moving Iron Cartridge

The Grado Aeon4 combines the Lineage Series' Brazilian ebony construction with a high-resolution nude Shibata stylus mounted on a sapphire cantilever. Its patented moving-iron flux-bridger generator is designed to convey subtle detail, instrumental colour and rhythmic control without exaggeration. Internal high-purity copper wiring and meticulous resonance management complete this hand-built reference cartridge.

Reference-level moving-iron design

Unlike conventional moving-coil designs, the Grado flux-bridger generator uses a moving-iron element with fixed coils. The Aeon4 is a low-output model and needs an appropriately matched high-gain phono stage.
