The M400 brings the entire architecture of the M800 — the topology, the state-of-the-art active power supply, the Class A bias scheme, the strikingly low feedback design — into a m ore accessible monoblock configuration. Four hundred watts into 8 ohms, doubling into 4. The same 30 watts of Class A bias, the same bandwidth exceeding 500 kHz, the same flat distortion profile across the audible band. The M400 isn’t a derivative of the flagship — it’s the same idea, scaled for systems and rooms that don’t need the M800’s full reserves. Designed by Darren Myers. Engineered into production by Bob Stadtherr. Hand built in Boulder, Colorado. Sold individually. For stereo, two M400 monoblocks.​ Show more
