Thank you for purchasing one of our second-generation Progression amplifiers. We are

thrilled with the enhanced performance we were able to achieve in the new Progression

M550 and S350 models.

There is no mistaking the D'Agostino family styling of the new Progression M550 Mono

Amplifier and the Progression S350 Stereo Amplifier. Immediately grabbing one's attention

is the unique heat sink design. Drawn directly from the Relentless Mono Amplifier, this

highly efficient elliptical form dramatically improves the cooling ability of the design and

assures that the Progression Amplifiers run safely and reliably even when delivering their

full rated power. A major revision of the input topology highlights the audio circuitry

improvements. The Progression M550 and S350 distortion, signal/noise ratio, channel

separation, and bandwidth measurements have all improved. Coupling this advanced

front end to a new output stage has improved the dynamic impact, tonal richness, and

spatial integrity of the amplifiers' playback.

A new transistor, first used in the Relentless Mono Amplifier, extends high frequency

response, increases power handling 50%, and features exceptionally tight tolerances for

gain matching between complementary pairs. Coupling the new output device to the high-

efficiency heat sink design affords an increase in operating bias and thus power. A core

belief of ours is that power is essential to great sound reproduction. The 550-watt output

of the Progression M550 Mono and the 350-watt/channel output of the Progression S350

Stereo offers something magical to a speaker. Of course they will play loud, but it is the

control of the speaker drivers that we desired. With virtually unlimited power output, the

Progression amplifiers deliver intimate musical details, three-dimensional sound staging,

and startling dynamics not possible from less capable designs.

From the start of Dan D'Agostino Master Audio Systems, one of our main goals was to

make components that perform at the top of their field yet are also the most beautiful

produced in the industry—we hope you agree. We are proud to say your amplifier was

built by hand at our Arizona factory, using advanced manufacturing techniques and the

best parts available, by a talented team of technicians and craftsmen. We hope you enjoy

the Progression amplifier as much as we enjoyed designing and building it, and hope you'll

keep an eye out for our future designs, too.

Sincerely,

Dan and the Team from Dan D'Agostino Master Audio Systems
