This “SL” model is a Low Output, Limited Edition version of the existing Kleos.
Although many MC cartridges have good performance, their sound is held back by how they are designed. The problem is, the signal coils should have the same angle as the magnetic circuit during playback, but MC cartridges are typically designed so that the opposite happens – applying normal tracking force pushes the coils out of alignment. This impairs coil sensitivity and linearity, and reduces sound quality.
Lyra’s “New Angle” technology solves this fundamental problem by compensating for how the signal coils are affected by vertical tracking forces, and optimally aligning the coils when it matters most – during playback. Introduced on our entry-level Delos, the New Angle technology enables the Delos to perform well above its pricepoint.
On mono records, the vertical axis of the groove contains no musical information, but it will frequently have noise, in the form of groove damage and dirt. The Kleos Mono has therefore been designed to be completely insensitive to the vertical axis, which greatly improves the signal/noise ratio without any downside on monaural records.
The coil former is a square permeable plate oriented parallel to the record surface rather than the 45-degree angle used for most stereo cartridges, while the coils are wound so that they only generate a signal when there is horizontal movement of the stylus and cantilever when tracking a record.
Two totally separate monaural coils are used in the Kleos Mono, since most monaural cartridges are used with stereo amplifiers and stereo speakers. The separate coils also help avoid possible ground loops and hum problems that could otherwise be caused if a single coil is fed into a stereo two-channel amplification system, thereby tying the two channels together electrically
Based in Tokyo, LYRA is headed by Stig Bjorge from Norway, with American design engineer Jonathan Carr, and Japanese master craftsman Yoshinori Mishima making cartridges and supervising production. All products are manufactured in Japan with microscopic attention to detail under the direct supervision of these three. LYRA products are characterized by advanced design engineering allied with Japanese artisanal craftsmanship and build quality.
