Ortofon Stylus 5S Replacement Stylus

Which cartridges is the Ortofon Stylus 5S built to fit?

The Ortofon Stylus 5S is a replacement stylus designed specifically for the Ortofon OM 5S and OM 1S cartridges. It is not a universal stylus; it is matched to these two cartridge bodies within the OM Series, so it will not fit other OM or 2M models correctly. This matters at the point of purchase because a stylus and cartridge body are engineered as a pair, and fitting the 5S to the correct OM 5S or OM 1S body preserves the tracking and compliance figures the combination was designed around. Buyers replacing a worn stylus need to confirm their existing cartridge model before ordering, since selecting the wrong stylus for a similarly numbered OM body will not deliver the intended tracking behaviour.

What does the spherical stylus tip mean for everyday tracking?

The Ortofon Stylus 5S is fitted with a spherical stylus tip, with a stylus tip radius of R18 µm. A spherical tip contacts the groove wall along a shorter, rounder area than finer-profile tips, which generally makes it more tolerant of groove wear and less demanding of precise vertical tracking angle alignment. The tracking ability figure of 60 µm at 315 Hz reflects this stylus profile, indicating the maximum groove modulation the stylus can follow cleanly at that frequency before mistracking occurs. This combination of tip shape and tracking ability supports stable playback and straightforward setup rather than requiring fine alignment adjustment to perform to specification.

How do you set the tracking force after fitting a replacement stylus?

The Ortofon Stylus 5S is rated for a tracking force range of 1.5 to 2.0 g (15 to 20 mN), with 1.75 g (17.5 mN) given as the recommended setting once it is fitted to an OM 5S or OM 1S body. Tracking force is set using the tonearm's counterweight and, where fitted, anti-skate adjustment, and it directly affects how consistently the stylus stays in contact with the groove walls. Setting the force below the recommended figure increases the risk of mistracking and audible distortion on loud passages, while setting it above the range increases stylus and record wear. The tracking angle of 20 degrees is fixed by the cartridge and stylus design, so no adjustment is required for this beyond correct arm height, which should position the cartridge body roughly parallel to the record surface.

What compliance and tonearm pairing does it require?

The Ortofon Stylus 5S is rated at a dynamic lateral compliance of 20 µm/mN, a figure that describes how readily the stylus suspension moves in response to groove modulation. This compliance value needs to be matched against the effective mass of the tonearm it is fitted to, since a mismatch between a high-compliance stylus and a high-mass arm, or the reverse, can produce a resonance point that falls within the audible or sub-audible range and affects tracking stability. With a cartridge weight of 1 g for the stylus itself, overall headshell and cartridge mass stays low, which supports pairing with lighter tonearms typically fitted to entry-level and mid-range turntables.

Where does the Ortofon Stylus 5S sit against other OM Series options?

The Ortofon Stylus 5S is positioned within the OM Series specifically as the replacement stylus for the entry-level OM 5S and OM 1S cartridges, rather than as a stylus for other models in the range such as the OM 5E or Super OM 5E, which are separate cartridges within the same series. Buyers who already own an OM 5S or OM 1S and need to replace a worn stylus should choose the 5S, since it restores the cartridge to its original specification without changing tracking force range or compliance. Buyers who do not yet own a compatible OM 5S or OM 1S body, or who are considering a different cartridge in the range, would need to select the matching stylus or cartridge for that specific model rather than the 5S, since stylus and cartridge pairings within the OM Series are model-specific.

What else does ownership of the Stylus 5S involve?

The Ortofon Stylus 5S is a component that benefits from protection when the turntable is not in use, and a stylus guard is available separately for the OM Series and CC MKI cartridges to cover the exposed cantilever and diamond tip. Fitting a guard between listening sessions helps prevent accidental contact, one of the most common causes of premature stylus damage. Because the 5S is a stylus rather than a full cartridge, replacement does not require realigning the cartridge body within the headshell, though tracking force should still be checked and reset after fitting to confirm it falls within the 1.5 to 2.0 g range for the OM 5S or OM 1S body.
