The Progression Mono has undergone a number of design changes during its development. The most powerful amplifier Dan D'Agostino Master Audio Systems has made to date, the Progression Mono delivers 500 watts into 8 ohms, doubling to 1,000 watts into 4 ohms and doubling again to 2,000 watts into 2 ohms.
The biggest design enhancements incorporated into the Progression Mono amplifier is our unique Super Rail. The Super Rail is a unique input/output stage power supply topology. Simple in description but complex in execution, the Super Rail uses additional higher voltage power supplies for the input stage than the main output stage. This higher voltage front end powers the Super Rail maximizing the output stage performance. Nearly ideal operation of the output stage results.
New but familiar aesthetics
The iconic look of the Momentum amplifiers' power meters, inspired by the elegant faces of classic Swiss watches, continues with the Progression Mono. The Progression Mono amplifier features a new meter design with a 270-degree needle swing, driven by a high-speed ballistic circuit that improves 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 Progression Mono amplifier by using a larger diameter opening for enhanced cooling capability from each heatsink. Each heatsink is milled from a single, 48.5-pound (22-kilogram) aluminum billet.
Design thoughts from Dan...
"With the Momentum series amplifiers, I focused on combining high power output with a relatively small form factor. But I knew some of our customers had a desire for a larger, more powerful amp at a somewhat more affordable price, that's why we created the Progression series."
