The Lyra Helikon is the first cartridge of Scan-Tech’s fourth-generation design architecture. […] The Helikon’s most notable advance is in the elimination of as much conductive material as possible from the vicinity of the generator and gap.

The design principles behind the Lyra Helikon ~
To strive for the most rigid mounting of the cantilever system achievable …
To optimize the movement of the stylus and coils relative to the LP grooves and the cartridge’s magnetic system.
To allow depleted vibrational energy to escape completely into the tonearm instead of reflecting back into the coils and generating inharmonic “echo” distortions.
To use a symmetrical, linear, stable magnetic system …
To create an invariable, linear magnetic field that the coils can rely on as a solid reference for signal generation.
To allow the cantilever and coils equal freedom of movement in all angles pertaining to groove tracking.
An overall performance goal for the Lyra Helikon was to create a more useable output level and a higher level of energy than the model it replaced (the Lyra Clavis DC) while maintaining the accurate reproduction of atmosphere, musical timbre and detail that has become the hallmark of all Lyra phono cartridges.
