Specifications for LYRA SKALA

  • Designer: Jonathan Carr
  • Builder: Yoshinori Mishima
  • 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 vertical pillar
  • Coils: 2-layer deep, 6N high-purity copper, square-shaped chemically-purified high-purity iron former, 5.4ohm self-impedance, 9.1uH 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. 12 x 10-6cm/dyne at 100Hz
    Vertical tracking angle: 20 degrees
  • Cartridge body: Two-piece composite structure, each piece controlling resonances within the other: Vertical "pillar" is one-piece machining from spring-grade phosphor bronze solid billet, with reduced-surface higher-pressure headshell contact area; horizontal "body" is one-piece machining from high-loss polymer, with threaded brass inserts 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): 9g
  • Recommended tracking force: 1.65 ~ 1.75g
  • Recommended load directly into MC phono input: 95.3ohm ~ 816ohm (determine by listening)
  • 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 adjustment
