Delos | MC Phono Cartridge

$2,595.00

The new Lyra Delos is designed to conquer some MC problems. Compared to conventional cartridges, the Delos has a new body structure with an unusually shallow angle, and this has been paired with a unique asymmetrical damping system. When no tracking force is applied, the shape of the asymmetrical dampers forces the signal coils and core into a more upright angle than the magnetic circuit.

However, no tracking force applied means that the cartridge is not operating, and therefore any angular discrepancies between magnetic circuit, signal coils and core will have no effect on performance. When tracking force is applied, however, the force of the stylus pushing on the LP causes the asymmetrical dampers to be deformed into a symmetrical shape, and when this happens the angular discrepancies between magnetic circuit, signal coils and core all disappear. Since tracking force applied means that the cartridge is now operating, it should be clear that the design of the Delos is able to keep the angles between the magnetic circuit, signal coils and core aligned during playback.

Keeping the proper angular alignment prevents the formation of any strong and directional flux that could otherwise flow constantly from the magnetic circuit into the signal core, and enables the Delos’ core to move with equal ease in all directions, for optimal performance.

The Delos also has a microridge stylus on a boron cantilever for outstanding tracking, a non-parallel solid machined metal body for low resonances, and 6-N high-purity copper coils and nude construction for greater clarity. The result is clearly improved sound quality, particularly resolution, tracking ability, dynamic range, transient impact and immediacy.
