The latest LP S incorporates a higher mass brass frame for improved coupling to tonearms, evolved ruby square plate generator and Ebony body. Brass, an alloy of copper and tin, complements Ebony, materials used for building musical instruments. The LP S has 50% more mass than the previous model for enhanced vibrational and resonant characteristics, thus revealing greater dynamic contrasts, deeper bass and increased resolution from all records. The latest LP S Class was the first Benz to use the new MicroRidge stylus, now found on all Benz Swiss-made cartridges.
