Specifications for LYRA KLEOS
- Designer: Jonathan Carr
- Builder: Yoshinori Mishima (final build, testing), Akiko Ishiyama (preliminary 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
- 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: 35dB or better at 1kHz
- Compliance: Approx. 12x10-6cm/dyne at 100Hz
- Vertical tracking angle: 20 degrees
- 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
- Cartridge mounting screws: 2.6mm 0.45 pitch JIS standard
- Distance from mounting holes to stylus tip: 9.5mm
- Cartridge weight (without stylus cover): 8.8g
- Recommended tracking force: 1.65 ~ 1.75g (1.72g recommended)
- Recommended load directly into MC phono input: 95.3ohm ~ 816ohm (determine by listening, or follow detailed guidelines in user manual)
- Recommended load via step-up transformer: 5 ~ 15ohm (step-up transformer's output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable)
- Recommended tonearms: High-quality pivoted or linear tangential) tonearms with rigid bearing(s), adjustable anti-skating force, preferably VTA
