Stabi R turntable, 4POINT 9 tonearm, CAR-40 cartridge

Stabi R

The STABI R is very much a modern take on an old concept – the turntable motor unit. At the dawn of high-end audio, hobbyists used to buy motor units and platters to build into home-made plinths. The STABI R offers the same opportunities for audio adventures, the same potential for cost-savings in producing a genuinely high-end record player, but it does so without imposing the necessity to apply your DIY skills.

By providing a selection of ready-made armboards and other options, the STABI R allows each owner to configure a unit specific to their needs, budget and aesthetic tastes. Of course, if you fancy a bit of woodwork – or even construction in more advanced materials – the STABI R allows that too …

The massive chassis is machined from a solid block of aluminium and, even after the necessary voids and hardpoints have been created, weighs over 25 kg. It sits on four adjustable feet to facilitate easy levelling and supports the proven, precision main-bearing and platter components from the STABI REFERENCE 2 turntable. These consist of an inverted bearing with a large diameter, diamond polished shaft, the sub-platter spinning on a ruby ball.
The mass of the 8 kg main platter is supported by a thrust pad and sleeves of a specially selected, low-noise, nonresonant material, with both the thrust pad/ball interface and the sleeve ring running in dedicated oil baths to further reduce friction and mechanical noise.

Our sophisticated three-phase DC motor and stiff, precision-machined polymer belt, deliver the speed stability and dynamics of direct or idler drive systems along with the acoustic isolation of belt-drive. Both the motor and its power supply are internal to, but mechanically and electrically isolated from the plinth, speed being electronically selected via two discrete buttons, inlaid in the top of the plinth. The high-torque motor and stiff belt accelerate the platter from stationary to 33.3 RPM in under two seconds – or a single revolution of the record.

Kuzma Wood Plinth

Stabi R Kuzma Wood Plinth

For those who want all of the sonic benefits of the highperformance STABI R motor unit in a compact package of more conventional yet still modern appearance – and don’t want to get out their woodworking tools – we offer a beautifully crafted wooden plinth that fits over the STABI R motor unit and supports tonearms of up to 12” in length. With an elegant profile built in Walnut, the Kuzma Wood Plinth combines the considerable musical advantages of the STABI R with an aesthetic to suit any domestic environment.

Arm mounting options

Side Mounted Arm Wing

This two-part, milled from solid armboard is machined in dedicated left and right-hand versions that can be mounted on either side of the STABI R motor unit. The cantilevered support element is topped with a separate arm board, the two-part construction inhibiting resonance and allowing the arm-mount to be changed to accept a different arm should you upgrade at a later date. A maximum of two arms can be mounted using the Side Mounted Arm Wing.

Arm Balcony

A simple, one piece angle bracket that bolts directly to the side of the Stabi R plinth. Pre-drilled for a specific arm, the Arm Balcony allows users to mount up to two tonearms, one in the conventional position and one across the back of the deck. Two different models are available, compatible with arms with a P2S mounting distance equivalent to either 9” or 12” arms of conventional design. Both versions of the Arm Balcony can be used in conjunction with either the Side Mounted Arm Wing or one or more Arm Holders to accommodate multiple tonearms on a single STABI R motor chassis.

Arm Holder

A tear-drop shaped arm mount, the narrow end can be fixed to any of the top-mounted bosses fitted to all four corners of the STABI R chassis. By adjusting the angle at which the Arm Holder is set, users can alter the P2S mounting distance to accommodate any conventional tonearm of up to 12” effective length, or longer still if the arm uses an off-set mount. With careful selection of tonearms and their arrangement, the Arm Holder allows owners to mount a maximum of four tonearms on the STABI R chassis. Drilled for Kuzma mount as standard, the Arm Holder can also be drilled to accept other tonearms with effective lengths between 9” and 12”.
