Ceramic spacer

Overview
The high-purity alumina cartridge spacer is bright white and compact (22.5 × 17 × 1.5 mm). Manufactured with modern ceramic processes, it delivers balanced mechanical properties to improve tonearm stability and tracking accuracy.

Key benefits

• Increased stiffness: optimizes mechanical response for more stable resonance
• Enhanced detail and realistic tonal presentation
• Compact dimensions and cost-effective solution for tonearm upgrades
• Reusable packaging for secure transport and storage
• Precise mechanical matching to achieve consistent resonance behavior

Applicable scenarios

• Home high-fidelity audio systems
• Vinyl record enthusiasts and collectors
• Tonearm upgrades aimed at sonic optimization
• Consumer and professional audio equipment
• Audio R&D and repair workshops

Performance

• Single seamless casting (monolithic construction)
• Material: high-purity alumina (alumina ceramic)
• Thickness: 1.5 mm
• Weight: 1.8 g
• Surface behavior similar to thin glass
• Significantly reduces headshell resonance
• Compatible with standard 1/2" (12.5 mm) cartridge mounting system
• Resonance measured by accelerometer vertical sweep (0–20 kHz): shows higher rigidity and more stable resonance performance

Note
Some cartridges require very light or intentionally resonant headshells; those models may not benefit from a ceramic spacer.
