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!
The Linn Keel sub-chassis upgrade is an ultra-high quality machined, single piece aluminium unit that replaces both the steel Linn Cirkus sub-chassis and the armboard, taking rigidity between bearing and arm to new levels.
Consequently, the lossy interface between the steel sub-chassis and the armboard, formerly achieved with three self tapping screws, is removed. This connection between the steel sub-chassis and the original main bearing was essential in the days before the Linn Cirkus bearing, as it acted as a filter limiting transmission of unwanted vibration and noise passing from the main bearing into the arm and cartridge. This is why, when unknowing enthusiasts replaced these small screws and the job that they were doing with larger ones, or worse still, with bolts through the sub-chassis and arm board making the connection more solid, the effect was to degrade sound quality. This is due to the increased transmission of the noise that was being produced in the original design. So, you can see that use of the Linn Keel sub-chassis is only possible because of the improvements that were made with the Linn Cirkus bearing.
Every design aspect of the Linn Keel affects its overall sound quality. Features such as the detail in the webbing on its underside, to the three raised areas beneath the main bearing (lands) so as to ensure a consistent contact area between it and the main bearing, all come together to create dramatic sonic improvements. This, combined with the integrated arm collar, thus eliminating the need to bolt one onto the sub-chassis with the small but consequential loss of integrity, means that the Linn Keel is a leading piece of audiophile engineering and design for the Linn Sondek LP12. The Keel for Linn arms is a complete and very well thought out solution, which allows so much more information retrieval from your record collection.
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.
In addition to the Keel designed for use with Linn arms, Linn kindly embarked on a project to enable the same sonic upgrade to be achieved using the Naim Aro tonearm, the Linn Aro Keel as it has come to be named.
Peter Swain of Cymbiosis was instrumental in facilitating this development with Linn, from the ideas phase, right through to the supply of arms that were tested in Glasgow at Linn HQ, so as to ensure the very best results were obtained with the Naim Aro.
Given the unique nature of the Naim Aro, the idea of an arm collar like that used on the Linn Keel was considered and rejected, as to have an integrated collar would have constituted a modification of the Naim Aro design itself. Consequently, a flat surface just like on the standard armboard is provided for the fitting of the Aro’s arm base.
The webbing on its underside is individual to the Linn Aro Keel and is precisely optimised for the Naim Aro. There is provision not only for the attachment of the Aro arm cable plug and arm rest, but also a specific area designed and pre-marked to facilitate the drilling of a fixing hole and attachment of Naim’s Aro arm lift called the Aromatic.
The Linn Aro Keel allows a Naimed Sondek LP12 to be upgraded to the same performance level as a top-flight Linn Sondek LP12.
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
The Linn Cirkus kit is the most fundamental and cheapest upgrade possible for your Sondek LP12, provided your deck does not have one already fitted. Introduced in 1993, the key features and components of the Linn Cirkus bearing and sub-chassis kit are:
