Close inspection of the Skala gradually reveals a central structure consisting of a vertical metal blade that carries the cantilever system, the magnets and the output pins, i.e. the entire functional core of the cartridge. The blade is clamped against the tonearm headshell by an outer white plastic base into which are drilled the mounting screw holes. Looking from the rear, you can see that the vertical blade passes right through the base and makes direct contact with the headshell. Since the cantilever system is also mounted directly to the blade, the cantilever has in effect a seamless connection path to the tonearm.
The metal blade of the Skala in effect functions without the resonant carapace of a traditional shell, in addition to being "nude" like the other Lyra designs.
The small contact "footprint" of the blade focuses the force imparted by the mounting screws, creating a high-pressure contact area which forms a more rigid bond between Skala and tonearm headshell than the larger mounting surface of a conventional cartridge could provide. The white plastic base forces the vertical metal blade of the Skala against the tonearm's headshell, and serves to constrain and damp resonances in the blade, and to reduce conductive material in the total body structure reducing eddy currents.
