Replacement stylus for the premium 2M Bronze moving magnet cartridge. All 2M cartridges' styli can be interchanged with replacement styli from the rest of the series, but the 2M Bronze and Black have a superior cartridge body, when compared to the 2M Red and Blue. You will therefore not get the full performance of a 2M Black by placing a 2M Black Stylus on a 2M Red body - though the sound will be vastly improved. Similarly, a 2M Red Stylus will be a notable downgrade to a 2M Bronze or Black cartridge.
