Linn Kore Sub-Chassis

The Kore is Linn's mid-range sub-chassis for the LP12 — the component that ships as standard on the Linn LP12 Selekt Turntable, and the correct structural upgrade for Linn LP12 Majik owners taking their first significant step beyond the standard Majik sub-chassis. At £976, it sits between the standard Majik sub-chassis and the reference Keel SE in the LP12 upgrade hierarchy — and its position there is not a compromise. The Kore delivers a disproportionate improvement in structural performance for its price, addressing the LP12's most fundamental mechanical variable — the sub-chassis — with an engineering rigour that the standard Majik sub-chassis cannot approach, and at a price point that makes it the natural first structural upgrade for any LP12 owner ready to move beyond the entry specification.

The sub-chassis is the mechanical heart of the LP12's suspended design. It carries the bearing, the armboard, and the tonearm — the three components whose relative geometry defines the cartridge's relationship with the groove. Any energy stored in the sub-chassis is energy returned to the cartridge as delayed, spurious signal — colouration that sits on top of the recorded information and degrades it. The Kore's construction is built around a single engineering objective: maximum rigidity, minimum stored energy, in a structure whose every joint and bond is designed to eliminate the compliance and resonance that less disciplined sub-chassis designs introduce into the signal path.

Three-Layer Bonded Aluminium — A Unified Structure

The Kore is constructed from three layers of 1.5mm aluminium, bonded together with a specialist adhesive to form a unified box structure. The bonded assembly is not a laminate in the conventional sense — once the adhesive has cured, the three layers behave as a single component, with no independent movement between them and no mechanical boundary at which energy can be stored or reflected. The bonding process is the critical manufacturing step: the adhesive is selected for its ability to lock the layers together with a rigidity that approaches the mechanical behaviour of a single-piece machined component, at a fraction of the material cost and with a structural geometry that a single billet cannot achieve at equivalent dimensions.

The armboard is machined separately from solid aluminium — not bonded sheet, but billet-machined to the tolerances that correct cartridge geometry requires — with reinforcing ribs on its underside that resist the torsional loads imposed by tonearm mounting and cartridge tracking force. It is then bonded to the sub-chassis assembly to form a complete, unified structure. The arm collar bolts directly to the sub-chassis, providing the shortest possible rigid load path between the tonearm pivot point and the bearing well — a directness in the mechanical structure that is one of the primary performance advantages of the Kore over the standard Majik sub-chassis, where the connection is less controlled and the energy path correspondingly less defined.

What the Kore Achieves

Upgrading from the standard Majik sub-chassis to the Kore is one of the most cost-effective structural improvements available on the LP12. The improvement is immediate and fundamental: less energy stored in the sub-chassis means less colouration returned to the cartridge. Bass becomes tighter and better defined. The soundstage stabilises. The LP12's characteristic sense of pace and timing — its PRAT — becomes more pronounced, because the rhythmic information in the groove is being retrieved by a cartridge that is no longer receiving contamination from a resonant sub-chassis beneath it. The Kore does not alter the LP12's fundamental character. It removes interference from it, and what remains is more clearly and confidently itself.

The Kore pairs naturally with the Linn Arko Tonearm at Selekt specification, and works correctly with the Linn Karousel Bearing Kit — which should be fitted to any LP12 that does not already have it, as a matter of priority, before or alongside the Kore upgrade. For power supply, the Kore is appropriate at Lingo level and above, and is the correct sub-chassis for a Radikal-equipped LP12 that has not yet committed to the Keel SE.

Kore vs Keel SE — The Structural Choice

The Keel SE represents the pinnacle of LP12 sub-chassis engineering — a single-piece machined structure of extraordinary precision that eliminates every joint, bond, and interface that the Kore's construction retains. The performance difference is real and audible, and the Keel SE is the correct specification at Klimax level. The Kore, however, is not an inferior version of the Keel SE. It is the correct engineering response to a different price point — one that delivers the same fundamental engineering philosophy through a different construction method, at a cost that makes it accessible to a far wider range of LP12 builds. For the Majik LP12 owner, the Kore is the upgrade. The question of Keel SE belongs to a later conversation, when the rest of the specification supports it.

Technical Specifications

Who Is It For?

The Kore is the correct upgrade for any Majik LP12 owner taking their first significant structural step, and for anyone building a Selekt-level specification from individual components. It is a permanent upgrade — not a stepping stone to be replaced in the near term, but a component that will remain relevant until the full reference specification of the Keel SE is the right decision for the system as a whole. At its price, the Kore delivers a structural and musical improvement to the LP12 that no other single upgrade at equivalent cost can match. It is the correct answer to the question of where to begin a serious LP12 upgrade programme.

Buying from Martins Hi-Fi

Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind.

Fitting the Kore requires full LP12 disassembly, tonearm transfer, and complete suspension setup — professional installation is essential, and we carry this out as part of our LP12 servicing work. If the Kore is part of a broader upgrade — alongside a Linn Karousel Bearing Kit installation, a tonearm change, or a power supply upgrade — we will plan the complete sequence with you before any work begins, ensuring each component is fitted in the correct order and the deck leaves our workshop correctly set up in every respect.

When you get in touch, you'll be speaking with Dave, Chris and Tim — experienced specialists who can advise on this product and your whole system.
