Linn · LP12 upgrades

The 2021-generation Radikal in its machined Klimax enclosure with the Urika II digital phono stage: Klimax-level drive for the Sondek LP12 and a lossless Exakt Link connection to a Linn DS or DSM.

Two components, fitted together; requires an Exakt-enabled Linn DS or DSM. The machined 2021 Radikal is a previous-generation part, so confirm availability.

The story

This package pairs the two components an LP12 needs for Linn's internal phono stage. The Radikal in the machined Klimax enclosure (2021 generation) replaces the deck's AC motor and supply with a brushed DC motor in an acoustic housing and an FPGA-managed controller that checks speed on every rotation, and it provides the power for a Urika inside the plinth, which cannot be fitted without a Radikal. This is the 2021 Radikal in the 60 mm chassis machined from solid aluminum, the version fitted to Klimax LP12s until the 2025 Klimax Radikal replaced it; Linn's current list carries the Klimax Radikal and the Radikal (Standard), so ask us to confirm availability.

The Urika II digitizes the cartridge signal inside the deck, applies RIAA equalization in the digital domain with per-unit calibration, and sends it losslessly over Exakt Link to a Linn DS or DSM with Exakt sockets; gain and loading are set in software for your cartridge. It needs an Exakt-enabled Linn player in the system. Alan Sircom in Hi-Fi+ concluded that "the detail, the timing, and the atomic-clock like precision win."

Each component is described in full on its own page. Fitting the pair is a single workshop visit: the motor is changed, the Urika mounted on its Trampolin board, the suspension set and the deck calibrated. The alternative packages pair the machined Radikal with the Urika, or either Urika with the Radikal (Standard).

Key technologies

  • Radikal DC motor and FPGA control. Speed checked on every rotation; powers the Urika.
  • Urika II. Digital RIAA with per-unit calibration and Exakt Link output.
  • Integrated Trampolin. The Urika mounts on its own suspended base board inside the plinth.
  • One installation. Motor change, phono stage fitting, suspension setup and calibration in one workshop visit.
