Grado The Reference 4 Phono Cartridge

The Grado The Reference 4 phono cartridge interfaces with standard half-inch tonearms via precision four-pin terminals, offering demanding vinyl collectors an exceptionally accurate transducer for high-fidelity playback. Positioned at the apex of the wooden-body Timbre Series, this cartridge employs hand-wound oxygen-free continuous-cast copper coils paired with a low-mass moving iron generator to extract intricate harmonic information. Configured in both High Output and Low Output variations, the unit delivers consistent electrical linearity across both moving-magnet inputs and high-gain phono preamplifiers.The Hi-Fi Centre Team TakeLiving with this cartridge transforms extended album sessions into deeply engaging, fatigue-free listening experiences where instrumental textures and natural acoustic decay emerge effortlessly.
