The 890.FS is the first cartridge to be shipped with 2 types of styli and is designed for use with DVS. The 2 spherical styli are designed for scratching and general playback. The 2 elliptical styli are designed for hi-quality playback for recording of records into the DVS system or any other application where sound quality is critical. The 890.FS also includes a stylus mountable dust brush which sweeps dusts off of the groove of the record during playback and recording.
The MP4 package includes 2 matched cartridges, mounted on tone-arm like devices, inside a small and practical road-worthy clear "flight-case".
