Momentum Monoblock Amplifier

Audiophiles know Dan D’Agostino as the world’s most skilled and passionate designer of audio electronics, and the first to champion the use of high-powered solid-state amplifiers in high-end audio. With the Momentum monoblock amplifier, he begins anew with revolutionary concepts, innovative materials and a fresh-slate design. The momentum sounds warmer, more musical, more alive than any other amplifier Dan has designed—and any other amplifier, period.

Momentum Monoblock Amplifier

Achieving what was once thought impossible: incredible power and incomparable finesse in a compact chassis.

Creating an amplifier that could meet all the demands of today's audiophiles required two things: one of the world's most talented and experienced designers, and a clean slate.

The Momentum is the first amplifier offered by Dan D'Agostino under his own name. As, cofounder and former Chief Engineer of Krell Industries, D'Agostino has earned a reputation for building the world's best high-end amplifiers.

With the Momentum, he begins anew, using all the experience he gained in 40 years of designing amplifiers but starting entirely fresh, with no need to adhere to past concepts.

No other amplifier looks like the Momentum. No other amplifier sounds like the Momentum.

Revolutionary Cooling

The Momentum is the first production amplifier to use copper for its heat sinks. The thermal conductivity of copper is 91-percent greater than that of aluminum, allowing the Momentum to use a much smaller heat sink.

To further enhance cooling capacity, the heat sink uses venturis instead of fins. The mouths of the venturis measure 0.75 in (1.9cm), and they narrow to 0.5 in (1.2 cm) in the middle. As the air in the top of the venturis heats and expands, the shape of the venturis forces it upward and draws more air in from the bottom. The venturi-equipped copper heat sinks make the Momentum’s compact, four-inch-high chassis possible.

Energy-Efficient Design

Most high-end audio amplifiers consume hundreds of watts of power the moment you push the “On” button—even when they’re idling and reproducing nothing but silence. With the Momentum amplifier, Dan D’Agostino has achieved a new standard in energy efficiency for the high-end audio industry. Despite its impressive output of 300 watts per channel into 8 ohms, the Momentum draws less than 1 watt of power at idle—or about one fifth of what a typical cell phone charger might require.

High-Speed Transistors

The 28 output transistors used on the Momentum are among the fastest high-output transistors available. They run at a blistering 69 MHz, permitting D’Agostino to achieve incredible bandwidth. Each transistor mounts with two stainless steel fasteners—a rarity among fl at-package transistors—for maximum thermal transfer to the copper heat sinks. A capacitor/resistor network connected to the base of each transistor ensures stability even at high frequencies and with low-impedance speakers.

A Build-Quality Benchmark

Hand-built and hand-tested in America, the Momentum’s chassis is machined from solid aluminum billet, not stamped from sheet metal. It is non-resonant and provides superior shielding from radio-frequency and electromagnetic interference (RFI/EMI).

The circuit board is assembled using through-hole construction, which resists heat (and stands the test of time) far better than the usual surface-mount boards can. Using through-hole construction also allows the use of higher-quality capacitors in the circuit. All resistors are 1% metal-film units. There are no capacitors in the signal path—the amplifier is DC-coupled from input to output.

The PIONEER OF HIGH-END, HIGH-POWERED AUDIO AMPLIFICATION

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.
