Descripción
The Audio Origami PU8 tonearm represents the culmination of more than two decades of tonearm design and refinement. Developed as the natural evolution of the highly regarded PU7, the PU8 advances every critical element of the design while preserving the stability and precision of our proven gimbal architecture.
At the heart of the PU8 is a newly engineered gimbal assembly designed for greater structural stability and control at the pivot. The gimbal housing is machined from a denser material to improve rigidity, working in conjunction with an enlarged Delrin bearing housing that enhances bearing support and reduces unwanted micro-movement at the pivot.
The armtube uses a constrained-layer carbon–aluminium composite construction, chosen for its excellent balance of rigidity and controlled energy dissipation. This structure is further refined by our Meta Material Arm Damping System, developed to manage energy within the arm while preserving the speed and clarity required for accurate groove tracing.
Together these design elements create a more stable and controlled platform for the cartridge. The increased effective mass, improved damping and greater structural integrity allow the stylus to track the groove with exceptional precision, revealing fine detail while maintaining tonal naturalness and musical coherence. By controlling resonances throughout the arm structure, the PU8 allows the cartridge to operate in a quieter mechanical environment, preserving subtle recorded information.
The result is a tonearm that combines high resolution with composure and balance, allowing cartridges to perform at their full potential while preserving the musical integrity of the recording.
PU8 Reference Tonearm unique features…
One of the fundamental challenges in tonearm design is controlling resonance while maintaining complete stability at the cartridge pivot. The PU8 Reference addresses these challenges through a series of carefully engineered solutions.
Enhanced Material Damping
By using high-grade stainless steel in the gimbal, pillars and mount, the PU8 has increased mass in an area that doesn’t alter effective arm mass but drastically improves resonance damping.
Carbon-Aluminum Armtube
By adhering an inner aluminium tube to an external carbon fibre tube, the new PU8 armtube is exceptionally well damped, stiff and light. This innovative design minimises resonance, ensuring a purer signal reaches your phono stage.
Improved Anti-Skate Device
The new PU8 anti-skate mechanism delivers meticulous cartridge performance across the entire surface of the record whilst keeping it away from the cue lever, making the arm easier to use.
Perfect Match for High-Performance Moving Coil Cartridges
The PU8 is designed to optimise the performance of your favourite low to medium compliance cartridges with compliance between 5cu and 15cu, unlocking their full potential.
Meta Material Armtube Damping System V2
Our next-generation M.M.A.D.S. effectively isolates internal vibrations, further enhancing clarity and detail by floating the internal wiring and blocking armtube resonance.
Future Proofed Modular Design
Due to the modular design of the PU8, it can be upgraded and supported for life, so if we make any enhancements to the design, you can apply them to your existing PU8.
