The Progression Preamplifier adds new features previously not included in a D’Agostino preamplifier. Most noticeably, the Progression Preamplifier features an optional digital module. The digital module adds coaxial, Toslink, and USB capability to the analog base model. A fully differential DAC handles PCM signals up to 24 bit/384 KHz and DSD signals up to 4xDSD (11.2 MHz). This digital module feeds a discrete, fully complementary and balanced analog signal path from input to output. Negative feedback is not used anywhere in the Progression Preamplifier, nor is it necessary. Open-loop distortion is less than < 0.006% and the open loop bandwidth extends to over 100KHz.

The digital module adds coaxial, Toslink, and USB capability to the analog base model. A fully differential DAC handles PCM signals up to 24 bit/384 KHz and DSD signals up to 4xDSD (11.2 MHz).

Also new is the Bluetooth technology featured in the included remote control. The Bluetooth backbone extends the range of the remote by a factor of five and eliminates line of sight limitations that are inherent in IR remote controls.

The volume control is realized with a stepped balanced resistor ladder, using high-linearity solid-state relays and discrete precision resistors. The bandwidth and transient response of the preamplifier circuitry are unaffected by volume setting. The Progression Preamplifier has two independent outputs that can be individually operated or used simultaneously for driving a second amplifier in a subwoofer based system.

Housed in a separate chassis, the power supply makes use of extensive electrical and magnetic shielding to keep radiated interference away from critical preamplifier circuits. Internal circuitry filters RF noise on the AC power, and compensates for asymmetric power waveforms and DC on the mains. A second DC output is included to power future Progression source components.

Two analog meters, inspired by Swiss watch faces, function as VU meters during music playback. When volume is adjusted, the meter needles change to volume setting indicators. After adjustments are made, the meters revert back to VU meter operation. The meters also function as balance indicators when adjusting balance.

Dan D’Agostino

No name is more closely associated with high-end audio amplifiers than that of Dan D’Agostino. During his career of more than 30 years, D’Agostino pioneered countless advances in the design of amplifiers, preamplifiers, CD players, and surround-sound processors. He is known as the audio industry’s most passionate promoter of highquality, high-powered amplification. Makers of the world’s finest loudspeakers rely on D’Agostino-designed amplifiers for their most important demonstrations.

Dan D’Agostino was founder and chief engineer of Krell Industries through 2009. Now, he embarks on a completely fresh start with a new organization and new state-of-the-art designs. The products that bear his name not only achieve new levels of sound quality, they also look like nothing he has built before—more compact, more distinctive, and more living-room-friendly.

The new Dan D’Agostino products also reflect his concern for the environment—an attitude uncommon in an industry where some amplifiers consume hundreds of watts even when they’re not in use. Through innovative power-supply design, Dan D’Agostino products consume only the slightest trickle of power at idle, so they run cooler and save energy.

The greatest testimony to the quality of D’Agostino’s new project, though, is that his name—in fact, his very signature—graces the front of each and every Dan D’Agostino product. Everything he has learned in decades of design and engineering the finest audio equipment has gone into the Momentum.

As impressive as these designs may sound on paper, the only way you can truly appreciate their warmth, detail and unmatched beauty is to hear them at your nearest Dan D’Agostino Master Audio Systems dealer.
