Lyra Atlas Lambda
The Atlas λ is Lyra’s new flagship phono cartridge. Why asymmetric? By literally misplacing the “barriers” to great sound that are present in every other cartridge today, a number of important performance benefits are realized.
First, different-shaped structures on the left and right sides of the cartridge body suppress the formation of standing waves within, resulting in a significant reduction of resonance-induced colorations. Second, the asymmetric construction offsets the front magnet carrier and its associated mounting system so that it is no longer in line with the cantilever assembly. This opens up a direct, solid path between the cantilever assembly and tonearm head-shell so that vibrations from the cantilever can be quickly drained away once they have been converted into electrical signals, again suppressing induced resonances.
Lyra remains the only cartridge manufacturer to mount the cantilever assembly directly into the cartridge body thereby achieving a seamless, totally rigid connection between the cantilever assembly and head-shell. The effectiveness of this system has been enhanced as a result of the asymmetrical structure of the Atlas λ Lambda. Control over spurious resonances is further assisted by the use of a narrowed mounting area, which couples the Atlas λ more tightly to the head-shell and facilitates the transfer of vibrational energy into the tonearm.
The Atlas λ Lambda uses Lyra’s “New Angle” technology, which mechanically pre-biases the signal coils so that they are perfectly aligned to the front and rear magnets when LP playback takes place. This equalizes out discrepancies in vertical and horizontal compliances and enables the Atlas λ Lambda coils to move with equal ease in all directions for optimal performance.
We firmly believe that the Atlas λ Lambda represents an important step forward in LP playback.
