Linn, Just Listen... Linn, based in Glasgow, Scotland, was founded in 1973 by Ivor Tiefenbrun. They are world leaders in digital streaming products as well as speakers, amplification and, of course, turntables, with the iconic Sondek LP12.
To get the best from your turntable, the bearing must be very quiet in motion and sit perfectly stable and true to the chassis. This in turn minimises the risk of turntable platter movement with respect to the sub-chassis and arm. Even the slightest movement will introduce audible degradation to the sound and will make an enormous difference to the performance of the turntable as a whole. So, the less movement and less noise introduced here, the better!
Keel SE has had rigidity and mass increased precisely where it is needed. Particular focus has been placed on the vital path between the mounting point for Karousel and the tonearm collar. The area between these has been stiffened up greatly – and for very good reason. Even the slightest rocking movement of a sub-chassis and armboard will modify the physical relationship between the tonearm and platter, negatively affecting the stylus’ tracking in the record groove. Making the path between bearing and arm stiffer ensures that any change in geometry is minimised, reducing tracking distortion.
A new, better-balanced centre of mass has been established for the turntable’s total sprung mass to improve its behaviour. By extracting material from calculated areas beneath the armboard, a Keel SE fully loaded with platter, arm and cartridge has its centre of mass balanced more evenly on its suspension than Linn’s previous designs. This improves weight distribution between the springs, and reduces inertia of the sub-chassis’ extremities, improving the critical acoustic isolation properties of any LP12.
The Linn Kore sub-chassis and armboard is designed for extra rigidity and removal of unwanted damping, making it a perfect performance upgrade for your Linn Sondek LP12 turntable. It follows the design philosophies developed for the Linn Keel, but delivers a lower-cost solution at an Akurate level.
The Linn Kore sub-chassis is very rigid, being a multi-layer box construction using 1.5mm thick aluminium. The Linn Kore is comprised of three parts that are bonded together using a special Linn-specified adhesive, to form an incredibly stiff structure to which the armboard, machined from solid aluminium using a similar process to the Linn Keel, is then bonded.
The armboard has strengthening ribs machined onto its underside, again providing excellent stiffness and rigidity, enabling the sub-chassis and armboard to exhibit the properties of a single unit. The arm has a direct connection to the main bearing, as the arm collar is effectively bolted directly to the sub-chassis. With its innovative design and, very importantly, a price that is substantially less than that of the Linn Keel, we feel the Linn Kore is a very exciting and important new addition to Linn’s range of upgrades for the Sondek LP12.
The Linn Kore is available in four versions: for Linn arms, the Naim Aro, plus Rega and SME type mountings.
Linn have introduced a new bearing upgrade for the Sondek LP12 turntable.
Designated as the Linn Karousel, this is a new, innovative precision-engineered design which will improve vinyl reproduction from every LP12 ever made.
The unique single-point bearing, combined with the acoustic isolation of the turntable design, were the foundations on which Linn was established in 1973, the bearing design even providing the inspiration for the Linn logo.
Testament to its ground-breaking design, the basic principles of the bearing have remained and the Linn Karousel is only the third evolution of this design in almost 50 years.
This innovative take on the design for 2020 has been made possible by technological developments around the material science, machining capabilities and mechanical engineering expertise gained from almost half a century of designing and manufacturing the world’s best turntable.
The Linn Karousel bearing is supplied as part of a kit which also includes a new inner platter and service upgrade parts for the Sondek LP12*.
* Bearing kit includes: Karousel bearing, inner platter and spindle, 3 x springs, 3 x large grommets,
3 x small grommets, 3 x washers, 3 locknuts, earthing wire and oil
