M-900u
To bring out the best.
The M-900u Class A/B Stereo/Mono power amplifier is the pinnacle of Luxman's craft; a power amplifier built to bring the absolute best sound possible from any attached speaker system. From the lowest bass rumble to the highest, most delicate breaths of airy treble, absolute linearity is achieved with sufficient force by utilising 4 parallel push-pul outputs in parallel. Aditionally, Luxman's proprietary ODNF [Only Distortion Negative Feedback] circuit provides both a lively tone and ultra-low distortion in what is now version 4.0. The unit offers a large analogue meter to the joy of nostalgists, those acquainted with the glory days of analogue, and the free-spirited child in all of us, joined to a disarmingly minimalist exterior chassis of blasted white. While the unit is presented as a Stereo Power-Amplifier, the BLT connection also allows the option of utilising the M-900u as a Monaural [Mono] amplifier producing 600wRMS @ 8Ω.
