Grado Epoch 4 Phono Cartridge

The Grado Epoch 4 phono cartridge utilises a patented moving-iron flux-bridger generator housed in an acoustically damped Brazilian ebony body to provide reference-grade vinyl playback for discerning analogue listeners. Hand-assembled in Brooklyn, this flagship Lineage Series transducer combines ultra-high-purity copper coils with a low-mass motor mechanism to achieve moving-coil transient speed without excessive moving mass. The assembly couples a nude Shibata diamond to a solid sapphire cantilever, ensuring precise groove tracking and extended high-frequency resolution across complex pressings.The Hi-Fi Centre Team TakeLiving with the Epoch 4 transforms domestic playback into an intimate, fatigue-free listening experience that reveals the layered spatial acoustics of familiar pressings. The low 1.0 mV output delivers background quietness and dynamic freedom, allowing fine instrumental textures to emerge naturally during quiet late-night sessions. Its organic tonal balance and structural damping eliminate harsh mechanical resonances, presenting records with consistent composure and physical weight. It is an enduring investment for serious music lovers who demand absolute groove fidelity without sonic colouration.Key Acoustic & Design Features Sapphire Shibata Assembly: Combines a rigid sapphire cantilever with a nude diamond profile to maximise groove contact and high-frequency resolution. Flux-Bridger Generator: Employs a low-mass moving-iron architecture to deliver swift transient response while retaining exceptional harmonic stability. Brazilian Ebony Body: Utilises dense hardwood construction to dissipate internal mechanical vibrations and preserve natural acoustic timbre. Authorized Dealer Assurance: Purchased through Hi-Fi Centre as an authorized dealer, guaranteeing authentic manufacturer warranty coverage, dedicated customer support, and factory retipping access.
