MOMENTUM M400 MONOBLOCK AMPLIFIER
The Momentum amplifier helped launch Dan D'Agostino Master Audio Systems and delivered magnificently on the initial design goals of formidable power and incomparable finesse from a compact chassis. Chief Engineer and Designer Dan D'Agostino started an engineering exercise that resulted in an exciting new breakthrough that D'Agostino felt compelled to include in the Momentum amplifier. This research led to the substantial improvements included the new Momentum M400.
The new M400 moniker gives clue to a major part of the upgrade. Power output has been increased to 400 Watts. This is up from the original 300 Watts. The backbone of the power increase is a new ultra-quiet 1,800VA linear transformer - a 20% increase in size from the original. Coupled to this larger power source is a new output stage design that includes a number of major enhancements.
