The Dan D’Agostino Progression Mono amplifier is the largest and most powerful Dan D’Agostino Master Audio Systems has made to date, delivering 500 watts into 8 ohms, doubling to 1000 watts into 4 ohms and doubling again to 2000 watts into 2 ohms. Beefed up with 48 output transistors, a 4000 VA power supply transformer and nearly 100,000 microfarads of power supply storage capacitance, the formidable output of the Dan D’Agostino Progression power amplifier offers something magical to a speaker.
Circuitry
The Dan D’Agostino Progression circuitry borrows greatly from the flagship Momentum to be a perfect match for virtually any speaker. The audio signal path throughout is discrete, balanced and direct coupled. Advanced protection techniques shield the amplifier and associated components from any unexpected anomaly.
Design
Its design couples their core circuit topologies and introduces a new Dan D’Agostino Master Audio Systems topology, the Super Rail. Simple in description but complex in execution, 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 exceptional headroom for the output circuitry. Nearly ideal output stage operation results.
Swiss watch
The iconic look of the Momentum amplifiers’ power meters, inspired by the elegant faces of classic Swiss watches, continues with the Progression series. The Dan D’agostino Progression mono amplifier features a new meter design with a 270-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 heatsink design premiered in the Momentum amplifiers has been adapted to the cooling needs of the Dan D’Agostino Progression mono amplifier by increasing the diameter opening of each cooling tube opening. Each heatsink is milled from a single, 48.5-pound (22-kilogram) aluminum billet. Combining high power output and exquisite musical finesse, this amp delivers intimate musical details, three-dimensional sound staging and startling dynamics not possible from less capable designs. Like all their products, the Dan D’Agostino Progression series components are built by hand, by his team of craftsman and technicians, in his Arizona factory. The Progression mono is available in a silver or black finish.
