Noriyuki Miyajima has earned a worldwide reputation for his artisanal phono cartridges. The Infinity Mono is the company’s new top monaural model.

Miyajima’s new Infinity Mono is a further enhancement of the brand’s Zero monaural cartridge.

Miyajima Infinity Mono Cartridge

Miyajima has increased the size and weight of the Infinity compared to the Zero and has also optimised the single coil generator. The result is a sizeable cartridge, at 24mm wide by around 28mm deep and weighing in at just shy of 15g.

Mono Cartridge

Miyajima mono cartridges are true mono designs, which are mechanically different from a stereo cartridge. A true mono cartridge operates in the lateral plane only, with no vertical compliance. This insensitivity to vertical movement manifests as very low groove noise, as well as highly faithful tracking of the groove modulations.

Like all of Miyajima’s mono designs, the Infinity Mono features Miyajima’s vertical axis concentration moving coil generator system, which ensures that the cartridge responds accurately to the horizontal modulation of a mono signal.

Two Versions

The Infinity Mono is available in two versions: With a 1.0 mil conical stylus, suitable for wider groove mono records made from a stamper cut with a true mono cutting stylus (typically mono records made from the late 1940s to the late 1960s). With a 0.7 mil conical stylus, suitable for mono records made from a stamper cut with a stereo cutting stylus (generally mono records made from the late 1960s, including most modern mono reissues).

If you’re planning to play records from both periods, the 0.7 mil stylus is recommended although both styli will play all mono records – and far better than any stereo cartridge.

Like every single Miyajima cartridge, the Infinity Mono is crafted entirely in-house in Japan by Miyajima’s small, dedicated team.

Note: A true mono cartridge should be used solely with monaural records, not stereo.
