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 (3μm× 70μm), slot-mounted
Cantilever system: Diamond-coated solid boron rod with short one-point wire suspension, directly mounted into cartridge body via high-pressure knife-edge system
Coils: single layer, 6 N high-purity copper, chemically-purified high purity iron cross-shaped former, 1.52 ohm self impedance, 1.9μH inductance
Output voltage: 0.25mV@5 cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)
Frequency range: 10 Hz〜50 kHz
Channel separation: 35 dB or better at 1 kHz
Compliance: Approx. 12× 10 cm/dyne at 100 Hz
Vertical tracking angle: 20 degrees
Cartridge body: Multi-material (titanium, duralumin, bronze, stainless steel) self-clamping construction with reduced-surface higher-pressure headshell contact area, predominately non-parallel shaping, phase-interference resonance-controlling mechanisms, and body threaded directly for mounting screws
Cartridge mounting screws: 2.6 mm 0.45 pitch JIS standard
Cartridge weight (without stylus cover): 9.2g
Distance from mounting holes to stylus tip: 9.52mm
Recommended tracking force: 1.68〜1.78g (1.72 g recommended)
Recommended load directly into MC phono input: Determine by listening.
Recommended load via step-up transformer: 1〜10ohm (connect step-up transformer’s output to 10kohm〜47kohm MM-level RIAA input, preferably via short, low-capacitance cable)
Recommended tonearm: High-quality pivoted or linear (tangential) tonearm with rigid bearing(s), adjustable anti-skating force, preferably VTA adjustment
