Description
Replacement Stylus for SONY ND 25 E | BLACK DIAMOND
High-quality replacement stylus by analogis for the SONY ND 25 E cartridge – featuring a nude (solid), elliptical diamond from the BLACK DIAMOND series. This design ensures highly precise groove tracing, excellent detail retrieval, and clean, low-distortion playback across the entire frequency range.
What does “nude” mean?
Unlike bonded (tipped) diamonds, a nude stylus is made from a single, solid piece of diamond and is mounted directly onto the cantilever. This significantly reduces the moving mass of the stylus assembly. The result is improved transient response, finer high-frequency resolution, more accurate soundstage imaging, and reduced record wear.
Technical Specifications
- Stylus profile: Elliptical
- Diamond type: Nude (solid diamond)
- Recommended tracking force: approx. 1.5 – 2.0 g (typically optimal around 1.75 g)
- Compatible with: SONY ND 25 E

Sound & Performance
The elliptical profile allows for more accurate contact with the groove walls compared to conical styli. This results in cleaner inner-groove performance, clear and refined highs, and a controlled, well-defined bass response. Combined with the nude construction, the stylus delivers lively dynamics and excellent micro-detail retrieval.
An ideal choice for demanding vinyl enthusiasts who want to unlock the full potential of their SONY cartridge system.
