For your consideration, we have a rare Lyra Lydian Beta Moving Coil Stereo Phono Cartridge. The cartridge and stylus are in very good condition. The unit comes from a complete system that we purchased. The Lyra was mounted on a Fidelity Research tonearm on a Linn Sondek LP 12 turntable. It was a beautiful setup that sounded wonderful. The cartridge comes with the original box, mounting screws, installation manual, and warranty card. See pictures for further details of the cartridge and what is included. Note there are two pictures of the stylus taken under our digital microscope.
