Ortofon Stylus 310

Ortofon STYLUS 310 Replacement Diamond

The STYLUS 310 is a replacement diamond produced by Ortofon, a renowned Danish brand in the high-fidelity domain. This elliptical diamond is designed to fit the P-Mount (T4P) cartridges of Ortofon’s 300 series. It is compatible with Ortofon 310, 310U, and 320 cartridges, and can also be used to enhance the performance and sound quality of Ortofon 305 cartridges.

An Elliptical Tip Profile

The uniqueness of the STYLUS 310 lies in its elliptical tip profile. Unlike a classic conical tip that only touches the center of the groove walls, the elliptical tip more precisely follows the groove thanks to its reduced radius (0.3 x 0.7 mil).

This optimized contact allows the diamond to better capture the micro-information engraved and reproduce more details with better channel separation. The sound rendering gains in precision, clarity, and realism, especially in the high-frequency range.

A Nude Diamond for Greater Definition

The STYLUS 310 is equipped with a nude diamond, meaning a single-piece diamond without any metal part. Compared to a bonded diamond where the tip is glued onto a metal shank, the nude diamond offers a lower mass. This characteristic allows it to better follow the high-frequency undulations of the groove and extract more information with great fidelity. The sound reproduction is refined, with more definition in the highs and transients.

Reduced Tracking Force to Preserve Records

Thanks to its high compliance of 20 µm/mN, the STYLUS 310 requires only a low tracking force on the record, between 1.25 and 1.75 g. Ortofon recommends a setting of 1.5 g for optimal performance. This light touch helps reduce the wear on microgrooves and prolong the lifespan of vinyl records. The diamond itself wears out more slowly and maintains its performance longer.

Great Musical Versatility

With its extended frequency response from 20 Hz to 20 kHz and high reading capability, the STYLUS 310 diamond can transcribe all the subtleties of recordings, regardless of the musical genre. It reveals both the warmth of voices and acoustic instruments and the energy and impact of electronic productions. Precise and balanced, it respects the artistic message without coloration or distortion.

An Economical Solution to Upgrade Your Cartridge

Rather than completely replacing your Ortofon 300 series cartridge when the diamond is worn out, it is much more economical to opt for a STYLUS 310. Its installation takes just a few seconds without any modification. Moreover, replacing the original diamond with a STYLUS 310 on an Ortofon 305 cartridge significantly improves performance without changing the cartridge. It is a simple and affordable way to upgrade to a higher quality level.
