Skyanalog P-1M

The Skyanalog P-1M

The motor is derived from the P-2, featuring a square iron coil, an aluminum cantilever, and a conical diamond stylus manufactured in Japan.

A conical diamond stylus has a rounded tip with a constant radius, providing stable contact with vinyl grooves. It's durable, easy to maintain, and delivers reliable performance, making it ideal for casual listeners despite capturing less detail than other stylus shapes.

Technical Specifications

• Conical diamond stylus with a 5 µm radius and 250 µm length
• Aluminum cantilever
• Iron plate with cross-wound coils
• Aluminum housing
• Robust plastic stylus guard

Break-in Period

Approximately 30 hours at 23°C. Packaging includes screws and an Allen key for easy installation.

Sound Character

The sound is open, airy, and flowing, with full-bodied bass that complements silky, well-articulated mids and sufficiently airy highs, suitable for jazz, acoustic genres, and light pop-rock.

Technical note – system matching and headshell mass

During practical tests with Skyanalog cartridges on Technics SL-1200MK2, Technics SL-1200MK4, Technics SL-1200GR2 and Technics SL-1200G systems, a consistent mechanical behaviour has been observed in the low-frequency reproduction when using standard headshell configurations.
This behaviour is reproducible across multiple turntables and multiple samples of the cartridge.
In all cases, a clear improvement was achieved by increasing the total effective mass of the tonearm system, resulting in a shift of the system resonance into an optimal operating range.
This can be achieved through a combination of headshell mass and the use of an auxiliary weight mounted at the rear of the tonearm.

Practical configurations (Technics S-arm systems) (blue text are direct links)

Auxiliary weight 16 grams Technics Auxiliary Weight 16g
(Technics part references: TKKH51441 / TPAKK61)
→ recommended headshell mass: 11–14 grams
→ example: Audio-Technica AT-LH13H

Auxiliary weight 26 grams Technics Auxiliary Weight 26g
(Technics part reference: TPAKK62)
→ recommended headshell mass: approx. 17 grams
→ example: Nagaoka HS-10

The effective headshell mass is therefore not a fixed value, but depends on the total system configuration including the selected auxiliary weight.

Technical explanation
The most likely explanation is a mismatch between tonearm effective mass and the dynamic properties (compliance) of the cartridge, resulting in a system resonance that is slightly too high in the standard configuration.
By increasing the total effective mass, the resonance frequency is shifted into an optimal range (approximately 8–12 Hz). This results in stable tracking and a tighter, more controlled low-frequency response.

Conclusion
For Technics S-arm systems, correct adjustment of total effective mass — using headshell mass and/or an auxiliary weight — is essential for optimal performance of Skyanalog cartridges and maximum playback stability.

Stylus care
Use only a dry brush to clean the stylus. The use of cleaning fluids is not recommended, as it may damage the cantilever or suspension. Handle the stylus with care for optimal performance.

Break-in period
The cartridge requires an approximate break-in period of 30 hours at an average temperature of around 23°C. The packaging includes mounting screws and an Allen key for easy installation.
