Description

The Audio Technica AT-OC9ML/II is a high-end moving coil cartridge designed for the most discerning audiophile seeking the ultimate in analog audio fidelity. This model represents the evolution of the acclaimed OC9 series, incorporating proprietary MicroLine® diamond tip technology that ensures precise tracking of vinyl grooves with reduced distortion and longer record and stylus life.

The AT Vector-Aligned design uses two voice coils mounted at 90 degrees instead of traditional moving magnets, delivering exceptional channel separation (31 dB at 1 kHz) and precision stereo imaging that reveals every detail of the original recording. The gold-plated boron cantilever and square-shank bare stylus ensure optimal tracking and an extended frequency response of 15 Hz to 50 kHz.

Weighing just 8 grams and featuring a 100-ohm impedance , this moving coil cartridge integrates seamlessly with dedicated phono preamplifiers or amplifiers with a compatible MC input. The recommended tracking force of 1.25-1.75 grams and standard half-inch mounting make it compatible with most quality tonearms.

About the brand

Audio-Technica is one of the most respected brands in the global audio landscape: a Japanese company founded in Tokyo in 1962 that has conquered the global market thanks to technological innovation and build quality. Today, it is headquartered in Machida, in the Tokyo metropolitan area, and produces audio components for both home and professional use.
Audio-Technica was founded by Hideo Matsushita, who in the early 1960s hosted record listening sessions on high-quality systems in Tokyo and wanted to make high fidelity accessible to a wider audience. The company began with the AT-1 phonograph cartridge, followed by other models that allowed it to expand into new sectors: headphones and, later, microphones. Research and development remains at the heart of the business today, with constant attention to materials and precision construction.
Among the technical solutions that characterize Audio-Technica are the double magnet VM cartridges (Dual Moving Magnet) and, at the high end, dual-coil moving coil cartridges such as the AT-OC9X series, now in its fourth generation. In turntables, the brand offers both direct-drive and belt-drive models. In the headphone sector, the company develops its own drivers, both for professional use and for home listening.
Audio-Technica's product range spans several categories, with a longstanding specialization in analog: turntables, cartridges, and vinyl accessories, as well as headphones and microphones. In the turntable sector, available in the /product-category/sources/turntables/ section, the company offers solutions for every need, from the AT-LP60X automatic input model to the AT-LP7, a manual belt-driven turntable with a J-shaped tonearm.
The product series are divided into specific lines for specific uses and market segments. The AT-LP series represents the home turntable range, with automatic and manual models, many of which feature a built-in phono preamp and some with a USB output for digitizing vinyl, such as the direct-drive AT-LP120XUSB. The AT-OC9X line includes moving coil cartridges, from the version with an elliptical stylus to the versions with MicroLine and Special Line Contact styli. In the headphone sector, the ATH-M series is aimed at professional monitoring, while the ATH-AD range favors home listening with open-back headphones for a natural soundstage.
The ATH-M50x studio headphones are among the brand's most popular models in the professional world.
The target audience includes audiophiles, vinyl enthusiasts, and audio professionals looking for reliable components. The breadth of the product line, from entry-level turntables to high-end moving coil cartridges, makes Audio-Technica popular even among those new to the world of high fidelity.
