Goldring Ethos Moving Coil Cartridge

To ensure a cartridge reproduces an accurate transcription of the record groove, the cartridge components must be rigidly mounted to the tonearm, whilst simultaneously allowing the tiniest movements of the diamond stylus to be transmitted, via the cantilever, to the sensing coils. The Legacy boasts an ultra-low resonance magnesium metal body which is both very light and extremely strong.

For convenience and rigidity, it has threaded inserts allowing the cartridge to be easily mounted and accurately aligned into the headshell. The stylus is a very low mass 'Vital' fine line diamond, which is highly polished and gives extremely low distortion. To maintain rigidity, this is attached to a hard alloy cantilever which transfers the maximum level of detail from the diamond to the coils; the latter are hand wound using only the highest purity copper. To achieve the optimum compliance required to deliver a smooth, extended frequency response, the stylus damper is formed from a bespoke rubber mixture. Lastly, a precision, rare earth, Neodymium iron boron magnet helps deliver outstanding dynamics.

Line-Contact Stylus

The line-contact diamond profile provides a large contact area with the groove wall, improving the retrieval of high-frequency detail and reducing groove wear. Its vital-shaped shank has a low tip mass giving the design exceptionally good trackability.

Alloy Cantilever

The stiff and lightweight alloy cantilever tube has been tuned to the ideal length for cartridge stability and ride height. Its length has been optimised to reduce inertia in the suspension system and improve trackability.

Cross-Shaped Armature

The coils are wound around a cross-shaped armature of pure, high-permeability, Swedish iron. The reduced unsprung mass improves the ability for the stylus to track the groove wall and minimises cross-talk, improving the stereo image.

Optimised Suspension

The new damper pad uses a bespoke butyl rubber compound to keep the system critically damped. Combined with an expertly tensioned tie-wire, the cartridge remains ultra-stable even during the loudest and most complex passages.

Neodymium Magnet

A very light and powerful neodymium magnet is clamped between two pole shoes creating a perfectly uniform magnetic field gap, within which the cross armature is suspended. This gives Ethos its typically flat and extended frequency response.

Aluminium Body Shell

The body is precision-milled from a low density, rigid, aircraft grade aluminium which helps to maintain a low effective mass and enables it to dissipate unwanted resonances into the tonearm where they are effectively ‘grounded’.
