Commentary
Audiotechnica, which was established in 1962, announced the limited edition MC cartridge in commemoration of 33 years anniversary.
The basic configuration is based on AT33ML/OCC, and the version has been upgraded with original know-how.
A gold-evaporated boron solid cantilever is used to enhance the tracing capability in the middle and low range.
Clean transmission is achieved by using PCOCC (single-crystal high-purity oxygen-free copper) 6N for the coil and PCOCC for the terminal pin.
Uses neodymium magnet with high magnetic energy.
It uses a micro-linear needle with low distortion rate, enabling stable regeneration for approximately 1,000 hours.
