Keel SE

Top-performing machined sub-chassis and armboard

Keel SE is the highest-performance LP12 sub-chassis available, with superior stiffness, optimised resonant behaviour and ideal distribution of mass.

The intricate bracing structure machined into the underside of Keel SE – designed using a mixture of manual and computer-aided optimisations – has helped us to achieve our number one goal of increasing sub-chassis stiffness as much as possible. This significant 300% increase versus our previous designs means that any vibrations travelling through Keel SE have their frequencies forced higher, and their energy substantially lowered.

Optimised resonant behaviour allows Keel SE to better break-up and dissipate problematic acoustic energy, reducing its potential impact on the delicate music signal.

By machining aluminium from calculated areas beneath the armboard, Keel SE has its centre of mass balanced more evenly on its suspension compared to other sub-chassis models. This improves weight distribution between the springs, and reduces inertia, improving the critical acoustic isolation properties of any LP12.

Klimax Radikal

Reference motor control, motor and power supply

33.333333 is the magic number.

Klimax Radikal features hyper-accurate speed management technology; generating sustained, uniform rotation closer to 33⅓rpm than any turntable.

You’ll experience even more of your music, in perfect pitch, thanks to Klimax Radikal’s digitally managed motor control, bespoke Utopik power supply, and machined aluminium chassis with exceptional electrical and mechanical isolation.

The Utopik power supply is critical to performance, as it possesses separate, dedicated output voltage rails for each of Klimax Radikal’s two specialised tasks: controlling the motor and providing power to Urika internal phono stages. These output rails are separately self-regulating; any sudden, significant draws in power from the motor or controller don’t affect the rails supplying Urika, and vice versa. The independence of these rails ensures consistency and quality of power supplied to both the motor and phono stage, improving the performance of each.

Also critical to performance is Klimax Radikal’s enhanced mechanical isolation. Weighing in at nearly 14kg, machined from three pieces of solid aluminium, and mounted on high-mass stainless-steel feet with rubber ring inserts, its beautifully machined casework is reassuringly robust in the face of external influences.
