Commentary
MM type stereo cartridge that adopts special suspension wire system.
By adopting a vibrator support structure using a special suspension wire system, excellent transient characteristics, high compliance, and low distortion factor are realized by the synergistic effect with precision damper.
Uses inner magnetic type hard light alloy cantilever.
This is an internal magnetic structure in which a movable magnet is directly fixed in a thin straight pipe, and has a small effective mass, low mechanical impedance, uniform frequency characteristics, and excellent separation characteristics.
0.5 mil diamond needle is used.
The needle tip has a 0.2 mm square block diamond to minimize the effective mass and improve the accuracy of the needle tip polishing to prevent wear of records and needle tips.
