라이라(Lyra)는 미국의 저명한 카트리지 디자이너 조나단 카(Jonathan Carr), 일본의 카트리지 마스터 요시노리 미시마(Yoshinori Mishima), 그리고 노르웨이 경영인 스티그 비요르(Stig Bjorge)가 이끄는 명품 카트리지 전문 제작사입니다. 1985년에 설립된 라이라의 본사는 일본 도쿄에 있고 라이라의 카트리지는 모두 일본에서 제작됩니다.

Specs
- 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
- 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
- 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
- Tracking force: 1.65 ~ 1.75g (1.72g recommended)
- Recommended load directly into MC phono input: 95.3ohm ~ 816ohm (detailed guidelines in instruction manual, finalize by listening)
- Recommended load via step-up transformer: Use a step-up transformer designed for 3 - 6 ohms cartridge impedance (step-up transformer’s output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable)
- Recommended tonearms: Medium to Medium-High mass arms recommended, which is bulk of tonearm market
