The stylus is a complicated piece; a stylus is generally one of four types. The difference is in the shape of the tip of the diamond and how it sits in the grooves of the records.
There are four main stylus shapes, excluding a stylus for 78 RPM records as the grooves of 78s are wider than a typical 33 1/3 record and require a stylus designed particularly for these grooves.
Why does stylus shape matter?
The shape and construction of the stylus contribute to how well it replicates sound from your record, due to the access it has to the surface area of the grooves. It can also contribute to the wear and tear of your vinyl records over time. This will affect the price of the stylus. So if you value high-end audio and have a bit of extra cash to put into your turntable set-up, it’s worth knowing about the different types of styli and the benefits of each type. You may also want to be more selective about your stylus depending on whether you’re using it for DJing or playing records at home.
Stylus construction
But before we get into the differences of turntable styli, let’s take a step back to the shank construction. The stylus sits at the end of the cantilever within the turntable’s cartridge, which is connected to the tonearm. The stylus will be attached to the cantilever will be either a nude diamond or a tipped diamond. With a tipped diamond, it’s just that – the very tip of the stylus is diamond while the rest is metal – as opposed to nude diamond where the stylus is a whole diamond that’s glued to the cantilever. That being said, the latter is the premium option as it has a lower mass and tracks more accurately.
4 Types Of Stylus:
Spherical
Spherical, or conical, is the most common stylus type and are the least expensive. It looks a bit like the tip of a ballpoint pen up close. Because of their relatively large radius, spherical styli trace less of the smaller groove modulations that represent higher frequencies. The effects record wear from spherical styli is ripe for debate within the HiFi community. Some claim spherical styli produce the most wear on records because the contact area of the diamond is restricted to two specific points, while contenders claim that this produces less wear.
Elliptical
The next most common stylus type is elliptical, or bi-radial. Elliptical makes contact across a larger area of the groove wall due to its dual radii. This allows for more precise tracking, improved frequency response (especially highs), improved phase response, and lower distortion, particularly in hard-to-track inner grooves. These types of styli usually wear a bit faster, and you’ll need to pay attention to the cartridge and tonearm alignment for best results.
Hyper elliptical
A hyper elliptical is also known as Shibata, fine line, or stereohedron. As the name suggests, this type is the next stage of evolution of the elliptical stylus, sharpening the design to make greater contact with the record grooves. When properly aligned, this stylus offers excellent high-frequency performance, longer tip life, improved tracking, and lower record wear. Due to their advanced design and difficulty to manufacture, they’re more expensive than the elliptical stylus.
Micro-ridge
The micro-ridge or Microline stylus is the most advanced of the four styli types. The computer-designed tip comes close to the shape of a cutting stylus used to produce master discs. Their multilevel “ridge” shape allows this stylus to give the best high-frequency performance with an extended record and stylus life (when aligned correctly). They’re tough to manufacture and very expensive.
