The Progression combines remarkable
power and exquisite musical finesse.
A note from Dan D'Agostino
FOUNDER AND CHIEF DESIGNER OF DAN D'AGOSTINO MASTER AUDIO SYSTEMS
Thank you for purchasing the Progression monoblock amplifiers. I am thrilled with the
performance and aesthetic design of the Progression Mono amplifier. This design combines
two normally exclusive traits: remarkable power output and exquisite musical finesse.
With our flagship Momentum series amplifiers, I focused on combining high power output
with a relatively small form factor. But I knew many of our customers had a taste for even
higher power, and the space for larger amplifiers. That's why we created the Progression
series. With the larger size, we were able to use aluminum for the heat sinks, which reduced
material costs dramatically.
The Progression circuitry borrows greatly from our Momentum amplifiers. Its design
couples our 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, counterintuitively, 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.
A core belief of mine is that power is essential to great sound reproduction. With the
ability to deliver 2,000 watts into a 2 ohm load, the Progression Mono offers something
magical to a speaker. Of course, it will play loud but it is the control of the speaker drivers
that I was after. The Progression Mono maximizes the performance of your preferred
speaker, delivering intimate musical details, three-dimensional sound staging, and
startling dynamics.
The iconic 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.
Like all our products, I am proud to say the Progression series components are built by
"
hand, by our team of craftsmen and technicians in our Arizona factory.
I hope you enjoy the Progression amplifier as much as I enjoyed designing and building it,
and I hope you'll keep an eye out for our future designs, too.
Sincerely,
