Ortofon Stylus 30 Replacement Stylus

Ortofon Stylus 30

The Ortofon Stylus 30 is a replacement stylus assembly built for Ortofon's OM 30-series and SME 30H-series cartridge bodies, aimed at owners who want to restore original tracking performance rather than replace the entire cartridge. Ortofon positions the Stylus 30 in the middle of its numbered stylus range, above the Stylus 10 and Stylus 20 and below the Stylus 40, giving buyers a defined tier to match against their existing cartridge designation. Its nude fine line diamond, 20° tracking angle, and 1.5 g recommended tracking force are set for the OM 30-series specification, so the stylus suits someone continuing to use a compatible body rather than someone starting a system from scratch.

Is the Ortofon Stylus 30 the Right Replacement Stylus for Your Cartridge?

This replacement stylus is designed as a direct fit for a matching OM 30-series or SME 30H-series cartridge body, not as a standalone cartridge purchase. It suits owners who already have one of the compatible bodies and need to replace a worn diamond and cantilever, rather than buyers assembling a new turntable setup. Because the stylus and cartridge generator are matched by design, confirming cartridge compatibility is the first step before ordering, since fitting the wrong stylus tier won't restore correct tracking performance.

Which Cartridges Is the Ortofon Stylus 30 Compatible With?

The Ortofon Stylus 30 is recommended specifically for the Super OM 30, OM 30, OMP 30, OMB 30, LM 30, Concorde 30, SME 30H, LM 30H, and TM 30H cartridge bodies. Buyers need to match the stylus to one of these bodies, as the assembly and cartridge generator are designed as a matched pair rather than a universal fit across Ortofon's range. Fitting the Stylus 30 to any of these bodies restores the original OM 30-series specification without requiring a new cartridge, which leaves existing headshell wiring and tonearm alignment unchanged.

What Does the Nude Fine Line Stylus Profile Change About Tracking Accuracy?

This stylus's diamond is a nude fine line design, mounted directly to the cantilever rather than bonded through a metal sleeve, which lowers moving mass at the tip and lets it follow groove modulations more closely at higher frequencies. The Stylus 30 uses a fine line profile with a tip radius of r/R 8/40 µm, a shape that contacts a narrower, more consistent section of the groove wall than a spherical or elliptical tip. This construction directly supports the stylus's tracking ability of 70 µm at 315 Hz and its frequency response of 20 Hz to 20 kHz (2/-3 dB), since lower tip mass and closer wall contact both reduce tracing distortion at the frequency extremes.

What Tracking Force Does Correct Installation Require?

The Stylus 30's tracking force range is 1.25 g to 1.75 g (12.5-17.5 mN), with Ortofon recommending 1.5 g (15 mN) for most tonearms. The tracking angle is fixed at 20°, so cartridge alignment during installation should match this angle rather than being adjusted to suit the tonearm. Setting force outside the specified range increases the risk of uneven stylus wear and groove damage, since the fine line profile depends on consistent, correctly weighted contact to trace the groove wall accurately.

Which Tonearms Suit This Stylus's Compliance Rating?

The Stylus 30's dynamic lateral compliance is 25 µm/mN, a figure that determines which tonearms suit it, because compliance and effective tonearm mass need to be matched to keep cartridge-arm resonance within the optimal range for stable analogue playback. Buyers replacing a stylus on an existing OM 30-series cartridge can check their tonearm's effective mass against this compliance figure before ordering, rather than assuming any arm will suit the replacement stylus the way it suited the original.

How Does the Stylus 30 Compare With Other Styli in Ortofon's Range?

The Stylus 30 is positioned in the middle of Ortofon's numbered stylus range, above the Stylus 10 and Stylus 20 and below the Stylus 40. Buyers choosing between these tiers are matching a stylus to their cartridge body designation, since each numbered stylus is built for the corresponding OM- or SME-series body rather than being interchangeable across tiers. Someone with an OM 10 or OM 20-based cartridge needs the corresponding Stylus 10 or Stylus 20, while the Stylus 30 is the correct choice specifically for Super OM 30, OM 30, OMP 30, OMB 30, LM 30, Concorde 30, SME 30H, LM 30H, and TM 30H bodies. A buyer wanting a higher tracking specification within the same OM 30-series body family, rather than a different body altogether, would look to the Stylus 40 instead. Ortofon also lists a Stylus Guard for OM Series and CC MKI cartridges as a separate accessory for protecting the stylus assembly during storage or transit.
