Moving magnet (MM) cartridges
tend to produce a lush, mellow
sound. Most MM cartridges have
replaceable styli. Their high voltage
output, variety, and the availability
of stylus replacement make moving
magnet cartridges a great choice for
the beginner and audiophile alike.
The Hafler PH50B is specifically designed for moving magnet cartridges.
It will boost the signal to produce a -10 dB output while incorporating
a well defined RIAA curve preserve and transmit the original program
material with minimal coloration.

The Recording Institute Association of America (RIAA) figured out that in
order to reproduce the recording effectively, the high frequencies have to
be exaggerated. Upon playback, the reverse filter must then be applied –
resulting in a flat or natural sound.
