The Dan D’Agostino Momentum M400 is published in the latest issue of Hi Fi News. Ken Kessler continues the universal praise for the Momentum amplifier design awarding the coveted Outstanding Product designation.
“…It’s clear that the Momentum M400 was not going to show any limitations where power, speed, attack, control or other wattage- related matters are concerned…Rather, the M400 impressed me because it is a ‘gentle giant’. Anyone can throw barrels of power at a speaker – but harnessing and delivering such power to exhibit delicacy is akin to creating a supercar that rides like a limousine…”
Paul Miller’s measurements confirm the awesome power delivery of the Momentum M400 – “…In practice it bests this by some margin at 430W/8ohm and 810W/4ohm with a dynamic output of 475W, 940W and 1775W into 8, 4 and 2ohm and with a scary 3010W (that’s 55A) into 1ohm.”
Current Momentum mono amplifiers can be upgraded to the Momentum M400 performance level for a retail price of US $15,000/pr plus shipping both ways. Included in the upgrade, is the new 400W meter plate and all the electrical component upgrades.
