Why Proper Cartridge Alignment Matters
Misaligned cartridges are one of the most common — and overlooked — causes of degraded vinyl sound. When the stylus tracks a groove at even a slight angle, it increases distortion at the inner grooves of your records and can accelerate groove wear. A properly aligned cartridge ensures your stylus follows each groove exactly as the record was cut, delivering the full fidelity of your vinyl collection.
