Lyra Kleos SL Moving Coil Cartridge

An ultra-low-output special order cartridge for expert users.

The Lyra Kleos SL is a special, built-to-order version of Kleos for expert users with very high-gain, extra low noise phonostages, or a step-up transformer designed for phono cartridges of 2 - 3 ohms or less.

The Kleos SL may provide extra pure and pristine sound from an audio system that is optimized for a low-impedance, low-output cartridge. However, this may be accompanied with a lesser level of energy and power. Please contact our analog team if you are unsure about running such a low-output (0.25 V) MC phono cartridge.

The Kleos SL was designed by Jonathan Carr, with Akiko Ishiyama doing the preliminary build, and Yoshinori Mishima doing the final build and testing.

The cartridge body is one-piece, machined 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.

The recommended load directly into MC phono input is determined by listening.

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
