Grado Red4
Prestige Series · Moving Iron Phono Cartridge
Part of the Grado Prestige Series, the Red4 delivers a balanced and engaging presentation built on decades of cartridge design experience. It maintains the core performance principles that define Grado cartridges while offering broad system compatibility — controlled, coherent, and consistently musical.
Moving Iron Design
Built on Joseph Grado's patented flux-bridger principle — extremely low moving mass, fixed coil, and long-term signal consistency without the fragility of moving coil designs.
Bonded Elliptical Diamond
Elliptical profile on an aluminum cantilever for effective groove contact, reliable tracking, and a stable, controlled presentation across a wide range of recordings.
User-Replaceable Stylus
The stylus assembly is easily user-replaceable. All Prestige Series styli are interchangeable, offering long-term ownership flexibility across models.
