Grado Red4

Prestige Series · Moving Iron Phono Cartridge

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.

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.

◆

5N OCC Copper & Cryo Treatment
