The Atlas λ Lambda is Lyra’s new flagship phono cartridge. Why asymmetric? By literally misplacing the “barriers” to great sound that are present in every other cartridge today, a number of important performance benefits are realized.

Lyra Atlas λ Lambda

Rating is 0.0 out of five stars based on reviews
    • 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 (block dimensions 0.08w x 0.12d x 0.5h mm, profile dimensions 3um x 70um), 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
    • Body: Machined asymmetrical titanium with synthetic composite gemstone
    • Coils: 2-layer deep, 6N high-purity copper, cross-shaped chemically-purified high-purity iron former, 4.2ohm self-impedance, 11uH inductance
    • Output voltage: 0.56mV@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 x 10-6cm/dyne at 100Hz
    • Cartridge body: One-piece machining from solid titanium billet, with reduced-surface higher-pressure headshell contact area, predominately non-parallel and asymmetrical 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): 11.6g
    • Recommended tracking force: 1.62 - 1.72g
    • Recommended load directly into MC phono input: 104ohm ~ 887ohm (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
