Audio-Technica AT-OC9/III phono cartridge



"These cartridges are so competent and so well priced that they can't be ignored by their peers, and that includes some which cost several times as much."1

"The OC9/III is a clear step up from the 2M Bronze and a Concorde with a 40 stylus (basically an om40). More detail then either of those, wider/deeper soundstage, and less surface noise. It's also the best tracking cart I've ever had."2

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

Customer feedback indicates the AT-OC9III offers exceptional musicality and performance comparable to the best cartridge regardless of price.
