moving coil cartridge
Nevertheless, the most important element of the new Kleos is it’s sound. We firmly believe that the Kleos is capable of extracting more information from the vinyl grooves than it’s 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 it’s 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.
Lyra offers a unique combination of capable, advanced cartridge design by Jonathan Carr and complete handmade execution by the above mentioned individuals. Investing in a Lyra Kleos through an authorized retailer will offer you an unparallelled analog experience from your stereo microgroove vinyl records.
- Designer: Jonathan Carr
- Builder: Yoshinori Mishima (final build, testing), Akiko Ishiyama (primary build)
- Type: Medium weight, medium compliance, low-impedance moving coil cartridge
- Stylus: Lyra-designed long-footprint variable-radius line-contact nude diamond (3um x 70um), slot-mounted
- Body: Nickel-plated duraluminum
- Cantilever system: Solid boron rod with short one-point wire suspension, directly mounted into cartridge body
- Coils: 2-layer deep, 6N high-purity copper, square-shaped chemically-purified high-purity iron former, 5.4ohm self-impedance, 9.0uH inductance
- Output voltage: 0.5mV@5cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)
- Frequency range: 10Hz ~ 50kHz
- Channel separation: Greater than 30dB at 1kHz
- Compliance: Approx. 12×10-6cm/dyne at 100Hz
- Cartridge body: One-piece machining from solid 7075 alloy billet, with reduced-surface higher-pressure headshell contact area, partially non-parallel shaping, phase-interference resonance-controlling mechanism, and body threaded directly for mounting screws
