- Musical excellence with a great balance of dynamics, natural harmonics and detail retrieval

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-OC9 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. With the new Audio-Technica AT-OC9/III cartridge you will experience musical opulence and expressiveness of sound layered on depths of silence.
