Here’s a beautiful rare SONUS BLUE Moving Magnet Cartridge.
It has excellent frequency response, tracking ability and the lowest possible tracking force, which reduces album wear. The cartridge is very clean and it sounds great [not overly bright nor overly warm], with excellent imaging, separation, and dynamics. The soundstage is great with that 3-D sound. The stylus is sharp and clean showing very little wear.
Output Voltage: 5mV
Impedance: 47k ohms
Frequency response: 20Hz to 20,000Hz
Tracking force range: .75 to 1.25g
