About the M-900u

The Luxman M-900u is a flagship stereo/mono power amplifier from 2015, praised as one of the best-sounding amplifiers by reviewers for its exceptional build quality, tonal balance, detail retrieval, and soundstaging. It employs Luxman's advanced ODNF 4.0 (Only Distortion Negative Feedback) circuitry with a bipolar 4-parallel push-pull x2 output configuration, enabling overwhelming power linearity up to 1,200W into 1Ω (stereo) or 2,400W into 2Ω (mono). Operates in pure Class A up to 12W, then Class AB. Features a large-capacity 1,250VA EI-type super-regulation transformer for stable power delivery, high damping factor of 710 for superior speaker control, and BLT connection for monoblock use. Housed in a premium blasted white chassis with cast-iron footers and illuminated VU meters showing power output in dB. Compatible with Y-lug speaker terminals. No longer in active production but available used.
