Le MC ultime : version bas niveau de la célèbre Atlas, conçu par John Carr et fabriqué par Yoshinori Mishima. Cette cellule à très bas niveau (0.25mV) demande un préamplificateur phono de haute qualité, mais à cette condition c’est probablement une des meilleures cellules du monde.

Spécification :
• 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: Diamond-coated solid boron rod with short one-point wire suspension, directly mounted into cartridge body via high-pressure knife-edge system
• Coils: 2-layer deep, 6 N high-purity copper, chemically-purified high purity iron X-shaped former, 1.52 ohm self-impedance, 1.9μH inductance
• Output voltage: 0.25 mV@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 X10 cm/dyne at 100 Hz
• Vertical tracking angle: 20 degrees
• Cartridge weight (without stylus cover): 11.6g
• 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
