roksponsmallThe Progression mono amplifier is the largest and most powerful amplifier that the company has made, delivering 500 watts into 8 ohms, doubling to 1,000 watts into 4 ohms and doubling again to 2,000 watts into 2 ohms.

The Progression circuitry borrows greatly from our D’Agostino’s Momentum amplifiers. Its design couples their core circuit topologies and introduces a new Dan D’Agostino Master Audio Systems topology, the Super Rail. The Super Rail, counter-intuitively, uses additional higher voltage power supplies in the input stage than the main output stage. This higher voltage front end provides headroom for the output circuitry. It employs a fully complementary driver stage, outfitted with 84 output transistors—42 for the positive signal and 42 for the negative signal, a nearly 3,000 VA power supply transformer, and 400,000 microfarads of power supply storage capacitance.dan_dagostino_progression_monoblock_hifinews_oct

The look of the Momentum amplifiers’ power meters, inspired by the elegant faces of classic Swiss watches, continues with the Progression series. The Progression mono amplifier features a new meter design with a 90-degree needle swing, driven by a high-speed ballistic circuit that enhances the meter’s responsiveness. The longer swing allows the needle to cover the amplifier’s entire output range. The Venturi-style heatsink design premiered in the Momentum amplifiers has been adapted to the cooling needs of the Progression mono amplifier by enlarging the row of openings to each heatsink. Each heatsink is milled from a single, 48.5-pound (22-kilogram) aluminium billet. Pictured in silver, the Progression mono amplifier is also available in black.
