AUDIO-TECHNICA AT-OC9/III AT OC9/III ATOC9/III CARTRIDGE The Audio-Technica AT-OC9/III is the latest evolution of the Audio-Technica AT-OC9 cartridge originally launched in 1987. Over the years the Audio-Technica AT-OC series has undergone a number of model changes both inside and outside Japan, and it has continued to be a best seller for over 20 years. While drawing on the basic design of the Audio-Technica AT-OC9ML/II which has been available exclusively in overseas markets and which has received critical acclaim all these years, the Audio-Technica AT-OC9/III is the result of a fresh approach based on a thorough review of the stylus tip, cantilever, magnetic circuit parts, damper and other aspects designed to track and reproduce the highest sound quality.
