Joseph Grado, a Metropolitan Opera watchmaker turned audio engineer, founded the company in the back of his family's fruit store on 7th Avenue, hand-winding coils on a watchmaker's lathe and selling cartridges from the same building. Four generations on, the Grado family still operates out of that Sunset Park facility, where every cartridge is assembled by hand before it ships. The patented flux-bridger moving iron generator system at the heart of every Grado has been refined continuously since Joseph's original designs. It delivers the speed and detail retrieval associated with moving coil cartridges while keeping the higher output and simpler loading requirements that made Grado a fixture in working studios for seven decades.\u003c\/p\u003e\n\n\u003ch5\u003eFlux-Bridger Moving Iron System\u003c\/h5\u003e\n\u003cp\u003eAt the heart of every Grado cartridge is the flux-bridger generator, a moving iron design patented by the Grado family. Unlike moving coil cartridges that attach the coils directly to the cantilever, which adds mass, or traditional moving magnet designs that fix a magnet to the cantilever, Grado's system uses a small iron element as the moving component. This achieves the lowest effective moving mass of any generator type, allowing the stylus to track groove modulations with exceptional accuracy. The result is transient speed and low-level detail associated with moving coil cartridges, paired with the higher output voltage and simpler phono stage requirements of a moving magnet. For the Epoch4, Grado uses the most refined version of this generator. Components are hand-selected from a broader pool than the lower-tier Lineage models, tolerances are held tighter at every stage of assembly, and each finished generator is auditioned at the factory before being committed to a finished cartridge.\u003c\/p\u003e\n\u003c!-- Inline image 1 --\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-epoch4-inline-01.jpg\" alt=\"Grado Epoch4 flagship phono cartridge in Brazilian Ebony housing\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\n\u003ch5\u003eShibata Diamond and Sapphire Cantilever\u003c\/h5\u003e\n\u003cp\u003eThe Epoch4 uses a nude Shibata diamond stylus, a profile originally developed for quadraphonic playback that has become the standard for high-end cartridges due to its extended groove contact area. The Shibata profile sits deeper in the groove than elliptical or conical tips, reading information that simpler profiles miss while distributing tracking force across a larger contact patch. This reduces record wear at the same time as it improves high-frequency extension and inner-groove tracking. The diamond is mounted nude, meaning the gem itself is bonded directly to the cantilever rather than to an intermediate metal shank, which lowers tip mass and tightens the precision of energy transfer. That diamond is then mounted on a sapphire cantilever, chosen for its rigidity at extremely low mass. Sapphire transmits vibrations from the stylus tip to the generator with minimal energy storage, preserving micro-detail and transient attack that softer cantilever materials absorb.\u003c\/p\u003e\n\u003c!-- Inline image 2 --\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-epoch4-inline-02.jpg\" alt=\"Grado Epoch4 cartridge close-up showing nude Shibata diamond on sapphire cantilever\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\n\u003ch5\u003eBrazilian Ebony Housing\u003c\/h5\u003e\n\u003cp\u003eAll Lineage Series cartridges are housed in Brazilian Ebony, a dense tropical hardwood selected for its natural damping characteristics. The wood body absorbs airborne and mechanical vibrations that would otherwise feed back into the generator, reducing coloration and tightening bass response. Grado has refined the housing geometry for the \/4 generation, with updated profiles designed to improve both stability during playback and ease of installation. The Ebony body also contributes to the cartridge's 12-gram mass, providing enough heft for secure headshell mounting without requiring counterweight extensions on most tonearms. Each housing is finished by hand at the Brooklyn factory, and grain patterns vary from piece to piece, so no two Epoch4 cartridges look exactly alike.\u003c\/p\u003e\n\n\u003ch5\u003eUltra-High Purity OCC Copper Coils\u003c\/h5\u003e\n\u003cp\u003eOCC stands for ohno continuous cast, a copper drawing process that produces a single long-crystal structure with far fewer grain boundaries than ordinary copper. Fewer grain boundaries means fewer points along the conductor where the audio signal has to cross from one crystal to the next, which lowers distortion in the low-level signal coming out of a cartridge. Grado specifies OCC copper for the Epoch4's coils for the same reason it appears in reference-grade interconnects: the cartridge output is the smallest signal in the entire chain, and what gets lost or smeared at that stage cannot be recovered downstream. The Epoch4's coils are hand-wound at the Brooklyn factory and matched for channel balance before installation in the generator assembly, with tighter matching tolerances than any other model in the Grado lineup.\u003c\/p\u003e\n\n\u003ch5\u003eExplore the Full Grado Lineage Series\u003c\/h5\u003e\n\u003cp\u003eThe Epoch4 is the flagship of Grado's Lineage Series.

The Ebony body also contributes meaningfully to the cartridge's 11-gram mass, which gives most modern tonearms enough loading for secure tracking without requiring counterweight extensions or additional headshell weights. The wood is finished by hand at the Brooklyn factory, and grain patterns vary from piece to piece, so no two Aeon4 housings are identical.\u003c\/p\u003e\n\n\u003ch5\u003eUltra-High Purity OCC Copper Coils\u003c\/h5\u003e\n\u003cp\u003eOCC stands for ohno continuous cast, a copper drawing process that produces a single long crystal structure with far fewer grain boundaries than ordinary copper.

Joseph Grado, a Metropolitan Opera watchmaker turned audio engineer, founded the company in the back of his family's fruit store on 7th Avenue, hand-winding coils on a watchmaker's lathe and selling cartridges out of the same building. Four generations on, the Grado family still operates out of that same Sunset Park facility, where every cartridge is assembled, tested, and voiced by hand before it ships. The patented flux-bridger moving iron generator system at the heart of every Grado has been refined continuously since Joseph's original designs, delivering the speed and detail retrieval associated with moving coil cartridges while keeping the higher output and simpler loading requirements that made Grado a fixture in working studios and home systems for seven decades.\u003c\/p\u003e\n\n\u003ch5\u003eMachined Boron Cantilever\u003c\/h5\u003e\n\u003cp\u003eWhere the Epoch4 and Aeon4 use sapphire cantilevers, the Statement4 employs machined boron, a material prized in high-end cartridges for its exceptional stiffness-to-weight ratio. Boron transmits stylus vibrations to the generator quickly and accurately, with minimal energy storage that could smear transient detail. The machined construction, as opposed to drawn or bonded, ensures consistent diameter and wall thickness along the cantilever's length, which contributes to predictable behavior across the frequency range. Paired with the Shibata diamond's extended groove contact, the boron cantilever allows the Statement4 to deliver the Lineage Series' characteristic speed and resolution at its most accessible price point. The cantilever-stylus assembly is hand-aligned at the Brooklyn factory and inspected under magnification before final voicing.\u003c\/p\u003e\n\u003c!-- Inline image 1 --\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-statement4-inline-01_26146a25-2ef6-4d23-879a-05f6450b0004.jpg\" alt=\"Grado Statement4 phono cartridge in Brazilian Ebony housing\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\n\u003ch5\u003eFlux-Bridger Moving Iron System\u003c\/h5\u003e\n\u003cp\u003eThe Statement4 carries the same patented flux-bridger generator used throughout the Lineage Series. A small iron element serves as the moving component, keeping the effective tip mass lower than either moving coil or moving magnet alternatives. This low mass allows the stylus to follow groove modulations more accurately, particularly in complex passages where multiple instruments occupy similar frequency ranges. Unlike a traditional moving magnet design that fixes a magnet to the cantilever or a moving coil that hangs coils off the back, the flux-bridger keeps the cantilever assembly as light as possible while still generating the 1.0mV output that pairs cleanly with most MC-capable phono stages. The Statement4's generator is assembled and voiced to Lineage specifications, with hand-selected components that differentiate it from the Timbre Series models below.\u003c\/p\u003e\n\u003c!-- Inline image 2 --\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-statement4-inline-02.jpg\" alt=\"Grado Statement4 cartridge detail showing nude Shibata diamond on machined boron cantilever\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\n\u003ch5\u003eBrazilian Ebony Housing\u003c\/h5\u003e\n\u003cp\u003eEvery Lineage Series cartridge, the Statement4 included, is housed in Brazilian Ebony.
