Spherical and elliptical styli are the two most common types of styli used in turntable cartridges. They differ in shape, which affects their performance in different ways.
Spherical styli have a rounded tip, while elliptical styli have an oval-shaped tip. This difference in shape affects the stylus’s ability to track the record grooves.
Tracking is the process of the stylus following the modulations of the record grooves. Accurate tracking is essential for producing good sound quality.
Spherical styli have a larger contact area with the record groove than elliptical styli. This larger contact area makes spherical styli more forgiving of minor tracking errors. However, it also means that spherical styli are less able to track the finer details of the record grooves.
Elliptical styli have a smaller contact area with the record groove than spherical styli. This smaller contact area makes elliptical styli more susceptible to tracking errors. However, it also means that elliptical styli are better able to track the finer details of the record grooves.
Sound quality
The finer details of the record grooves contain high-frequency information. This high-frequency information is essential for producing a detailed and realistic soundstage.
Spherical styli are less able to track the finer details of the record grooves than elliptical styli. This means that spherical styli will produce a less detailed and realistic soundstage than elliptical styli.
Durability
Spherical styli are more durable than elliptical styli. This is because spherical styli have a larger contact area with the record groove. The larger contact area distributes the force of the stylus more evenly, which reduces the risk of damage.
Elliptical styli are less durable than spherical styli. This is because elliptical styli have a smaller contact area with the record groove. The smaller contact area concentrates the force of the stylus on a smaller area, which increases the risk of damage.
Which stylus is better?
The best stylus for you will depend on your individual needs and budget.
If you are looking for the best possible sound quality and don’t mind being more careful with your records, then an elliptical stylus is the way to go.
If you are looking for a more durable stylus and don’t mind sacrificing a bit of sound quality, then a spherical stylus is the way to go.
Here is a table that summarizes the pros and cons of spherical and elliptical styli:
| Characteristic | Spherical Stylus | Elliptical Stylus |
|---|---|---|
| Price | Less expensive | More expensive |
| Durability | More durable | Less durable |
| Sound quality | Good | Excellent |
| Suitability for older records | Suitable | May not be suitable |
| Compatibility with turntable cartridges | Very wide | Wide |
Both spherical and elliptical styli have their own advantages and disadvantages. The best stylus for you will depend on your individual needs and budget. If you are unsure which stylus to choose, it is always best to consult with a turntable expert. They can help you choose the right stylus for your needs and budget.
