The PU8 utilises high-density materials in the gimbal and mounting collar to effectively dissipate resonance.

Its advanced constrained-layer armtube further enhances performance, offering superior damping characteristics and robust protection for the internal signal path.

The Audio Origami PU8 features a carbon-aluminium composite armtube utilising a constrained-layer design.

This architecture effectively disperses resonant frequencies, preventing mechanical energy from compromising the cartridge's tracking and sonic performance.

While maintaining exceptional rigidity and a low-mass profile, the armtube further shields the internal wiring from vibration, ensuring the integrity of the signal as it traverses the tonearm.

M.M.A.D.S. is a specialised insert designed to decouple the internal wiring from the armtube.

By 'floating' the conductors within the arm, this structure prevents mechanical energy and resonance from degrading the delicate audio signal, thereby ensuring signal integrity.

Delrin is a high-rigidity acetal homopolymer prized for its high internal damping, which effectively dissipates mechanical vibrations as thermal energy.

By utilising Delrin at the gimbal interface, the PU8 isolates the precision bearings from parasitic resonance and provides a structurally damped housing for the armtube connection.

The effective mass of the Audio Origami PU8 is fully customizable to meet a client's specific cartridge requirements at the time of build. In its standard configuration, the PU8 is optimised for cartridges with a compliance range of 5–15 units (10−6 cm/dyne). A comprehensive breakdown of compatible cartridge pairings is provided above.

The PU8 is standard-equipped with Cardas Clear, a benchmark internal conductor known for its exceptional signal purity and low dielectric involvement. While we accommodate bespoke requests for alternative wiring, please note that Audio Origami cannot extend its warranty to third-party or customer-supplied cabling.

The Audio Origami PU8 is available in both Linn and Rega mounting configurations, ensuring seamless integration with the vast majority of high-end turntables.

This dual-format availability allows for near-universal compatibility across diverse armboard designs. If you require verification for a specific turntable model, please contact Stephen at stephen@audio-origami.co.uk for technical guidance.

Geometric parameters shift as tonearm length increases, necessitating precise calibration.

We recommend using a professional-grade instrument, such as the Dr. Feickert Protractor, to accurately establish the required pivot-to-spindle distance and ensure optimal cartridge alignment.

Vertical Tracking Angle (VTA) is easily calibrated on the PU8 by loosening two hex fasteners within the mounting collar.

This allows the base plate to be manually raised or lowered to the desired height.

The mechanism is designed for high efficiency, enabling precise height adjustments in under 30 seconds.

Azimuth is adjusted at the gimbal assembly by loosening two small hex fasteners on the Delrin bearing housing.

This allows for minute rotation of the armtube to ensure the stylus is perfectly perpendicular to the record surface.

We provide a precision headshell bubble level to establish an accurate baseline, though final micro-adjustments should be performed through critical listening to optimise stereo imaging and minimise crosstalk.

While the PU8 will continue to undergo iterative refinements in the years ahead, we are committed to offering an upgrade path for existing owners.

This policy ensures that your purchase remains a future-proof and sound investment, allowing your tonearm to evolve alongside our latest engineering advancements.

The Audio Origami PU8 is designed, machined, and hand-assembled in Scotland. 

To ensure the highest standards of mechanical performance, we source only a select few specialised components from outside the country: our precision-grade Japanese race bearings, high-purity internal conductors, and premium connectors.

While your authorised dealer is typically best positioned to assist with setup and compatibility, you may also refer to the Compatible Cartridge section above for technical data.

If you remain uncertain, please reach out to Stephen directly at stephen@audio-origami.co.uk for further guidance.

While we strongly encourage customers to purchase through our authorised dealer network to ensure expert setup and ongoing support, we recognise that some regions are not yet served by a local dealership.

In these instances, you are welcome to purchase your PU8 directly from Audio Origami.
