"To better understand how the Aesthetix works, remember that a moving coil phono cartridge is basically a coil of wire wound around a piece of iron (or ferrous material) suspended within a magnetic field. This electrical generator is activated by the phono stylus in the record groove, moving the wire coil and thus generating a signal to be amplified and reproduced by your loudspeakers. Think back to a simple science experiment placing a pin against a strong magnet for a few minutes. Afterwards, the pin, which is made of ferrous material, becomes magnetized enough to attract another pin.
Today's best moving coil phono cartridges use very strong magnets such as neodymium and samarium cobalt. When the moving coil absorbs some of the magnet's charge, the sound becomes murky and less defined. This is because the magnetized coil does not generate as great a variation as it moves within the magnetic field of the phono cartridge. "
