Wedge 1,5 deg sapphire
Precision sapphire wedge for critical stylus rake angle adjustment.
For the enthusiast seeking absolute precision in their analogue playback, this sapphire wedge offers a definitive solution for stylus rake angle optimisation. By fitting this extremely rigid component between the cartridge body and the headshell, you can achieve a fixed 1.5-degree adjustment that is otherwise impossible to obtain through tonearm height settings alone.
Positioned as a professional-grade tool within the Analogue Accessories line, the wedge is engineered for structural integrity and vibration transfer. Its composition ensures that the energy from the cartridge is coupled effectively to the tonearm, maintaining the clarity and focus of the signal without introducing resonance.
This accessory is essential for those who demand total control over their cartridge setup. By correcting the vertical alignment, it enables the stylus to track the groove with greater accuracy, leading to a noticeable improvement in harmonic resolution and transient response across the entire frequency range.
Key Features
01
Sapphire construction
Utilises the exceptional rigidity of sapphire to ensure a stable, vibration-neutral interface between cartridge and headshell.
02
Precision geometry
Provides a fixed 1.5-degree offset to correct stylus rake angle where tonearm VTA adjustments reach their physical limits.
03
Mechanical coupling
Ensures an extremely firm connection to maintain signal transparency and preserve the integrity of the cartridge output.
Chapter 01
The Purpose of Precision
The 1.5-degree sapphire wedge addresses a specific challenge in high-end vinyl playback: the deviation between a cartridge's ideal vertical tracking angle and the physical constraints of the tonearm mounting. By introducing this wedge, the user can shift the cartridge attitude to the perfect angle for the stylus profile, ensuring the most accurate groove tracing possible.
Chapter 02
Material Integrity
The choice of sapphire is deliberate. In an application where the smallest vibration can colour the sound, the extreme hardness and structural stability of this material prevent the loss of detail that might occur with softer shims or plastic spacers. It acts as an inert bridge, keeping the mechanical connection between the tonearm and cartridge pristine.

Listening Notes
Users will typically experience a greater sense of coherence and openness after correct installation. By aligning the stylus correctly within the groove, the wedge helps to resolve complex musical passages with less distortion, providing a cleaner, more articulate presentation that is true to the original recording.
