Specifications for Lyra Delos

• Designer: Jonathan Carr
• Builder: Yoshinori Mishima (final build, testing), Akiko Ishiyama (primary build)
• Type: Medium weight, medium compliance, low-impedance moving coil cartridge
• Stylus: Namiki microridge line-contact nude diamond stylus (2.5um x 75um), surface-mounted
• Cantilever system: Solid boron rod with short one-point wire suspension, directly mounted into cartridge body
• Body: Anodized aluminum
• Coils: 3-layer deep, 6N high-purity copper, square-shaped permalloy former, 6.3ohm self-impedance, 9.5uH inductance
• Output voltage: 0.6mV@5cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)
• Frequency range: 10Hz ~ 50kHz
