Grado Aeon 4 Moving Iron System Low Output

Grado Aeon4 MC cartridge

High-end precision with a musical soul

With the Grado Aeon4, Grado expands its renowned Lineage series with an exceptional high-end cartridge that combines audiophile precision with the brand's characteristic musicality. Developed based on decades of experience in cartridge manufacturing, the Aeon4 impresses with a remarkable combination of resolution, control, and natural sound reproduction.

At the heart of the design is Grado's patented Flux-Bridger moving-iron technology, which combines the speed and transparency of modern moving-coil systems with the sonic substance, stability, and longevity of a moving-iron cartridge. The result is a captivatingly balanced sound that will delight even the most discerning vinyl enthusiasts.

Authentic sound with exceptional detail

The Grado Aeon4 was designed for high-quality, high-gain phono preamps and delivers precise, controlled, and musical sound reproduction. The finest details are clearly rendered without sounding analytical or overly emphasized. The treble reproduction impresses with its smoothness and airiness, while voices and instruments in the midrange unfold with remarkable naturalness, presence, and richness of color.

In the bass range, the Aeon4 impresses with powerful dynamics, precise definition, and outstanding control. Even complex musical passages are reproduced with remarkable clarity and stability. The precise spatial imaging and excellent instrument separation create a realistic, three-dimensional soundstage that authentically conveys the character of every recording.

Shibata diamond and sapphire cantilever for highest tracking precision

For precise groove tracking, Grado uses a high-quality nude Shibata diamond stylus mounted on a particularly rigid sapphire cantilever. This combination enables excellent groove tracking, exceptional detail resolution, and remarkable dynamics across the entire frequency spectrum.

Thanks to the high stiffness of the sapphire, resonances are effectively minimized, allowing the Aeon4 to reproduce even the finest musical nuances with impressive clarity and stability.

High-purity 7N OCC copper for maximum signal purity

The Aeon4 uses high-purity 7N OCC copper (Ohno Continuous Cast). This material is characterized by its exceptional conductivity and homogeneity, ensuring particularly low-loss signal transmission.

In addition, each cartridge undergoes a complex cryogenic treatment. This process stabilizes the material structure and supports even more precise and consistent signal processing. Carefully developed internal damping reduces unwanted resonances and vibrations to a minimum and contributes significantly to the system's exceptional sound quality.

Elegant ebony cabinet with added acoustic value

The Grado Aeon4's housing is crafted from high-quality Brazilian ebony. Beyond its exclusive appearance, the wood performs an important acoustic function by controlling resonances and supporting the cartridge's natural tonal balance.

The optimized design reduces the system's mass and improves compatibility with a wide range of high-quality tonearms. At the same time, the open design provides a clear view of the cantilever and allows for particularly precise adjustment during installation.

Grado Aeon 4 – For discerning vinyl enthusiasts

With its combination of patented moving-iron technology, Shibata diamond stylus, sapphire cantilever, high-purity OCC copper, and elegant ebony housing, the Grado Aeon 4 offers exceptional performance for demanding analog systems. Anyone seeking a high-end cartridge that combines technical precision with musical naturalness will find the Aeon 4 a captivating partner for long-lasting vinyl enjoyment at the highest level.
