Audio-Technica Phono Cartridges AT-F7

The elliptical stylus has two radii, the front radius being wider than the side radius. This allows the stylus to ride in the centre of the groove, while the smaller side radius can more accurately track higher frequencies. The dual coil design of the AT-F7 provides outstanding clarity and transparency of tone along with improved frequency response and precise stereo imaging.
