The Kleos is the lowest cost Lyra cartridge to feature the full fledged Ogura manufactured boron canilever and coil system with Lyra original line-contact (3 x 70um) stylus. This is similar to what is employed on even the most expensive Lyra models.
Nevertheless, the most important element if the new Kleos is the sound. We firmly believe that the Kleos is capable of extracting more information from the vinyl grooves than its predecessors, and that the reproduction of music is both more dynamic, more detailed, and more natural than the models preceding it. We also are of the opinion that the Kleos will set a new standard for sonic performance at its price point.
Today there are only a small handful of master cartridge builders in the world, and Lyra's Yoshinori Mishima belongs to this elite group of individuals that are capable of crafting the highest level MC transducers on the planet. His assistant Akiko Ishiyama, who has undergone several years of apprenticeship, is also involved in the building process leading to each Kleos. The Kleos is not only hand made, but each cartridge is listened to extensively and "voiced" by the master cartridge builder, like the finest musical instruments.
Type: Medium weight, medium compliance, low-impedance moving coil cartridge
