In Stock	An In Stock item is available to ship normally within 24 business hours.
Preorder	A Preorder is an item that has not yet been released. Typically the label will set a projected release date (that is subject to change). If a projected release date is known, we will include this in the description in red. Other Preorders are set to release 'TBA.' This means that release date is yet 'To Be Announced'. The Preorder can be released anywhere between weeks, months or years from its initial announcement.
Backordered	An Out Of Stock item is an item that we normally have available to ship but we are temporarily out of. We do not have a specific date when it will be coming.
Awaiting Repress	Awaiting repress titles are in the process of being repressed by the label. No ETA is available at this time.
Expected On	When an item is Out Of Stock and we have an estimated date when our stock should arrive, we list that date on our website in the part's description. It is not guaranteed.
Special Order	A Special Order item is an item that we do not stock but can order from the manufacturer. Typical order times are located within the product description.

Epoch4 represents the highest level of performance within the Grado Lineage Series. Developed through decades of cartridge design and refinement, it reflects a continuous pursuit of musical accuracy, control, and resolution.

Built around Grado's patented moving iron flux-bridger system, Epoch4 delivers the speed and detail associated with moving coil designs while maintaining the tonal density, stability, and longevity that define Grado cartridges.

Offered in both stereo and mono configurations, Epoch4 is designed for systems where nothing is left to chance.

Performance

Epoch4 is a low output moving iron cartridge designed for use with high-gain phono stages.

Its presentation is defined by clarity, separation, and control. Detail is revealed without exaggeration, with a top end that remains smooth and composed. The midrange carries natural weight and texture, while low frequencies are delivered with authority and precision.

Complex recordings are resolved with ease, maintaining separation and spatial accuracy without collapsing the soundstage. The overall balance allows the character of the recording to come through naturally.

Flux-Bridger Moving Iron Design

All Grado cartridges utilize a moving iron design built on Joseph Grado's patented flux-bridger principle.

This approach allows the cartridge to generate a precise signal with extremely low moving mass, while keeping the coil structure fixed. The result is a presentation that combines speed, control, and harmonic integrity without the fragility often associated with traditional moving coil systems.

The design also ensures long-term consistency, maintaining performance over time without degradation of the internal signal path.

Diamond & Cantilever

Aeon4 features a nude Shibata diamond mounted to a sapphire cantilever.

The Shibata profile is highly effective at retrieving detail from the groove, offering exceptional contact and resolution while maintaining a natural, unforced presentation. Paired with a sapphire cantilever—known for its rigidity and resistance to deformation—the system delivers clarity, extension, and stability across the frequency range.

Coil & Internal Structure

The internal signal path is built using ultra-high purity 7N OCC copper, selected for its conductivity and consistency.

Each cartridge undergoes cryogenic treatment during both component preparation and final assembly, helping to stabilize materials and optimize performance.

The internal structure is carefully damped to reduce unwanted resonance and vibration, allowing the cartridge to extract information from the groove with minimal interference. The result is a signal that remains coherent, balanced, and dynamically responsive.

Housing

The Statement4 is housed in a Brazilian Ebony wood body.

Beyond its visual presence, the wood plays a role in controlling resonance and contributing to the cartridge's tonal balance. The structure has been refined to reduce mass while improving compatibility across a wide range of tonearms.

The form also improves visibility of the cantilever during setup, allowing for more precise alignment.
