Very old LPs that you’ve likely purchased second or third hand were almost certainly played many times with cartridges using spherical or elliptical or worn out styli of either type. When you then play those LPs with a modern cartridge using an exotic stylus shape of any kind, it’s likely that new stylus rides differently in the grooves, reading a more virginal path. This is the most likely reason for the perception that one cartridge is inherently quieter than another in terms of surface noise. That, plus elements of setup such as VTA. Beyond that, it’s phono stage design and cartridge loading.
