ZVUČNICA LYRA ARGO i (KLEOS) – MOVING COIL LOW OUTPUT

U ponudi je audiofilski dragulj “retip-an” u Lyra tvornici sa samo nekoliko (ali doslovno nekoliko) sati rada.
Retip-om je ugrađen kantilever, ovjes i igla od jačeg modela KLEOS, tako da sretnika koji ovu zvučnicu ugradi u svoj HI-FI sustav čeka praktično 3x skuplje i bolje rješenje od tvorničkog ARGO i-ja.
Specifications for Lyra Kleos
Designer: Jonathan Carr
Builder: Yoshinori Mishima (final build, testing), Akiko Ishiyama (preliminary build)
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
Body: Nickel-plated duraluminum
Cantilever system: Solid boron rod with short one-point wire suspension, directly mounted into cartridge body
Coils: 2-layer deep, 6N high-purity copper, square-shaped chemically-purified high-purity iron former, 5.4ohm self-impedance, 9.0uH 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: Greater than 30dB at 1kHz
Compliance: Approx. 12×10-6cm/dyne at 100Hz
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
Tracking force: 1.65 ~ 1.75g (1.72g recommended)
Recommended load directly into MC phono input: 95.3ohm ~ 816ohm (detailed guidelines in instruction manual, finalize by listening)
Recommended load via step-up transformer: Use a step-up transformer designed for 3 – 6 ohms cartridge impedance (step-up transformer’s output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable)
Recommended tonearms: Medium to Medium-High mass arms recommended, which is bulk of tonearm market
