M-700u, a power amplifier, is a new middle range model that inherits our powerful drive circuit including the latest version, ODNF 4.0 circuit whose distortion characteristics and S/N performance have been significantly improved and with which the top-end model, M-900u, has been equipped and also including 4-parallel push-pull structure with 3-stage Darlington to pursue Luxman's development philosophy for power amplifiers, "satisfying both high drivability and sound quality of high density". The output from 120 W/8Ω to up to 840 W/1Ω instantaneously exploits the full potential of speaker characteristics under any load conditions. M-700u is a new-generation stereo power amplifier that combines richly expressive sound and high power without losing the music dynamism.
