SPECIFICATIONS FOR KLEOS MONO
• Designer: Jonathan Carr
• Builder: Yoshinori Mishima (final build, testing), Akiko Ishiyama (preliminary build)
• Type: Medium weight, medium compliance, low-impedance, low-output moving coil cartridge
• Stylus: Lyra-designed long-footprint variable-radius line-contact nude diamond (3um x 70um profile, block dimensions 0.08 x 0.12 x 0.5mm), slot-mounted
• Cantilever system: Solid boron rod with short one-point wire suspension, directly mounted into cartridge body
• Coils: Two individually isolated monophonic/monaural 6N high-purity copper coils wound in parallel (on top of each other) on a square-shaped chemically-purified high-purity iron former with 3.0 ohms self-impedance
• Output voltage: 0.25mV@5cm/sec., 2.4μH inductance
• Frequency range: 10Hz ~ 50kHz
• 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 ~ 1.78g (1.72g recommended)
• Recommended load directly into MC phono input: Determine by listening,
• Recommended load via step-up transformer: Use a step-up transformer designed for 2 - 3 ohms cartridge impedance. The transformer output must be connected to standard 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
