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.\u003c\/p\u003e\n\u003cp\u003eThe Kleos SL was designed by Jonathan Carr, with Akiko Ishiyama doing the preliminary build, and Yoshinori Mishima doing the final build and testing.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe recommended load directly into MC phono input is determined by listening.\u003c\/p\u003e\n\u003cp\u003eUse a step-up transformer designed for 2 - 3 Ohms cartridge impedance.
