Linn Ekos SE Tonearm

Linn Ekos SE Tonearm

The Ekos SE is Linn's flagship tonearm — the reference against which every other arm in the LP12 range is measured, and the tonearm specified for the highest levels of Sondek LP12 performance. It is built from materials chosen not for cost or convention but for their acoustic and mechanical properties: a titanium arm tube machined to reduce resonance, a stainless steel bearing housing engineered for precision of movement, and ultra-low friction bearings with temperature-compensated precision springs that maintain consistent performance whether the arm has been playing for five minutes or five hours. The Ekos SE is hand-built to Linn's highest quality standard — a tonearm designed to last decades and to extract from a premium cartridge everything that cartridge is capable of.

Titanium Arm Tube — Resonance by Design

Titanium is chosen for the Ekos SE's arm tube for a specific reason: its resonant properties. Where aluminium is widely used in tonearm construction for its low mass and workability, titanium offers a different resonant profile — one that Linn's engineers have determined minimises interference and microphony in the frequency ranges that matter most for vinyl replay. The arm tube is machined from titanium, not formed or drawn — a process that allows tighter dimensional tolerances and a more consistent material structure throughout the tube's length. The result is an arm tube that manages the energy conducted from the cartridge through the headshell with greater precision than materials with less carefully considered resonant behaviour.

Stainless Steel Bearing Housing — Precision of Movement

The bearing housing of the Ekos SE is machined from stainless steel — a material chosen for its dimensional stability and its resistance to the wear and deformation that would, over time, compromise bearing precision in a housing made from less stable materials. The bearings themselves are ultra-low friction assemblies: the force required to initiate and maintain movement in both planes is kept as low as engineering allows, ensuring the arm responds to groove modulations rather than to its own bearing resistance. Temperature-compensated precision springs maintain the correct bearing preload across the temperature range a tonearm will encounter in normal domestic use — so the bearing behaviour the Ekos SE was set up to deliver is the bearing behaviour it maintains, regardless of the room's ambient conditions.

Long Headshell — Cartridge Compatibility

The Ekos SE is supplied with a long headshell that accommodates almost any cartridge currently in production. This is a practical engineering decision with real consequences: the geometry of overhang, offset angle, and effective length that defines a tonearm's tracking accuracy depends on the relationship between mounting distance and cartridge body dimensions. A long headshell removes the compatibility constraints that a shorter headshell imposes, ensuring that the Ekos SE can be optimally aligned with the full range of premium pickups — including Linn's own reference-level Ekstatik and high-performance Kendo cartridges, for which the Ekos SE provides optimum cartridge and tonearm synergy on the Sondek LP12.

T-Kable — Signal Integrity from Arm to Phono Stage

The Ekos SE is supplied with Linn's T-Kable in phono version — the tonearm cable that carries the cartridge's output from the arm's internal wiring to the phono stage input. The tonearm cable is a component whose contribution to signal integrity is frequently underestimated: at the signal levels a moving coil cartridge generates, cable capacitance, resistance, and shielding all influence what the phono stage receives. Linn's T-Kable is specified and designed as part of the Ekos SE system rather than as an afterthought.

Who Is It For?

The Ekos SE is for LP12 owners who have reached the point in the upgrade path where the tonearm is the component limiting further resolution — and who want the definitive Linn answer to that constraint. It is the correct arm for a Keel SE or Ekos SE-level build, and the natural partner for Linn's Ekstatik and Kendo cartridges. It sits above the Linn Krane Tonearm and the Linn Arko Tonearm in the range, and it belongs on an LP12 that has already been developed to a level where its capabilities can be fully realised — the Linn Klimax LP12 Turntable and the Linn LP12 Selekt Turntable are the builds in which the Ekos SE is most at home. For those at an earlier stage of the upgrade path, the Linn Karousel Bearing Kit and Linn Bedrok Plinth are the components to address first.

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.

The Ekos SE requires professional installation — arm collar alignment, cartridge mounting, suspension balance, and overhang geometry all need to be set correctly for a tonearm of this specification to perform as designed. We carry out the full installation on our LP12 service bench and will not return a deck until every parameter is verified. If you are considering the Ekos SE as part of a broader upgrade — alongside a Keel SE sub-chassis, Karousel bearing, or Ekstatik cartridge — speak to us first about the correct sequence and the most effective route to the build you are targeting.

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