Linn Klimax Radikal

Klimax Radikal is Linn’s reference-tier motor control unit and power supply for the Sondek LP12 — the flagship motor upgrade that brings any existing Sondek LP12 to Klimax-level speed stability and mechanical isolation. It is one of the four defining component upgrades that separate a Klimax-spec LP12 from a Selekt or Akurate specification (the others being the Keel SE arm board, Bedrok plinth, and Ekstatik cartridge).

The Radikal uses digitally-managed motor speed control that monitors every platter rotation, ensuring near-perfect 33-1/3 and 45 rpm stability across the life of the turntable. Its heart is Linn’s bespoke Utopik power supply, which uses separate, self-regulating voltage rails for motor control and internal phono circuitry — so both sections perform without interfering with each other, an engineering discipline that carries directly across from Linn’s approach to source components at every tier.

Built into a precision-machined aluminum chassis weighing nearly 14 kg and mounted on high-mass feet, the Radikal delivers outstanding mechanical and electrical isolation. Combined with the Keel SE arm board and subchassis and a Bedrok plinth, an existing Sondek LP12 (Majik, Selekt, or Akurate specification) can be brought to complete Klimax specification without ever buying a new turntable — the demonstration of the Sondek platform’s upgrade discipline in its most literal form.

At $16,820 in current Linn pricing, the Klimax Radikal is available at LMC. Walk in during business hours or book ahead — this is the upgrade discussion best had with the specific LP12 turntable and system context you are looking to develop.
