Fidelity Research Cartridge




The most advanced cartridge in the FR-1 series, the FR-1MK3F was the first MC cartridge in the world to use pure silver wire for the coils. As a conductor, pure silver has lower resistance than any other metal. Therefore, efficiency is greatly improved without the need to make any other alterations in cartridge design.

As with our other MC cartridges the famous FR-1MK3F has a coreless coil to prevent hysteresis distortion. For the stylus we employ a solid diamond with a line contact tip. This increases the area of contact with the groove walls, thereby greatly improving high-range response, long a problem area in cartridge design.
