Bisono Audio is a small workshop in Scotland, where each tonearm is designed, built, measured and set by the same hands.
Bisono Audio is founded on the better part of a decade developing products for high-end audio brands — deep in the detail of turntable, tonearm and cartridge design, including manufacturing partnerships with established European specialists.
That background is the reason Bisono exists. Years spent inside the detail of turntable and tonearm design — where a tolerance, a bearing preload or a thread tension quietly decides how a record is read — made one thing plain: most of the compromises in analogue playback are inherited, not necessary.
Bisono designs from the groove out. A tonearm is treated as one continuous mechanical and acoustic path, not a set of parts to be optimised in isolation and marketed with claims that rarely survive scrutiny.
Every decision is documented and tested before it is committed. Where a conventional solution drifts, wears or depends on assembly luck, it is replaced with something that holds true across decades of ownership. The aim is not novelty — it is fewer compromises between the record and your system.
Production is intentionally low in volume. Each Stratos is assembled and calibrated by hand, to a standard that does not vary from one unit to the next, using precision CNC partners for the parts that demand it and hand-finishing for the parts that reward it.
Before any design reaches a dealer, it is proven on a dedicated development platform used only for private evaluation — so that what is offered for sale has already earned its place.
