D’Agostino Momentum Stereo

Discontinued replaced by Momentum S250 MXV

Power Amplifier. The Momentum stereo amplifier delivers the extraordinary sound quality of the Momentum monoblocks in an affordable stereo design.

The circuit topology and construction of the stereo amplifier mirror those of the monoblock, using the same ultra-efficient copper heat sinks with venturi cooling, the same 1% metal-film resistors, the same 69 MHz output transistors and the same fully complementary balanced configuration.

The result is audio fidelity equaled by no other amplifier—except, of course, the Momentum monoblock itself—and an efficient design that consumes less than 1 watt of power at standby.

The distinctive power meter from the monoblock makes an encore appearance in the stereo amplifier, with a separate indicator needle for each channel. Like the monoblock, the stereo amplifier uses through-hole construction and is hand-built and individually tested in D’Agostino’s Connecticut facility.

Owners of the stereo amplifier who wish to upgrade to dual monoblocks can do so easily and affordably, because the stereo amp can be refitted by D’Agostino for mono operation. The resulting amplifier will be identical to a factory-fresh monoblock amplifier.

Momentum also available in silver/ Copper

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 35 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 high-quality, 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. Since the inception of DDMAS in 2011, energised with a new organisation 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 else in the industry. The new designs combine an elegant aesthetic flair coupled to inventive circuit topologies and innovative materials. Starting with the Momentum Mono amplifier, the D’Agostino product line now extends upwards to the awe inspiring Relentless Mono amplifier and outwards to the new Progression Integrated amplifier. The Relentless Mono Amplifier is an all-out assault on the amplifier category. Capable of driving any speaker to its fullest capability, the extraordinary power output of the Relentless Mono is only matched by its sublime low volume sound quality. The Progression Integrated amplifier connects the high-performance core of D’Agostino products to the exciting world of streaming audio with Tidal, Quobuz, and Spotify services as standard offerings. They are proud to say the Progression series components are hand built in the USA, by their team of craftsmen and technicians, in their Arizona facility. As impressive as these designs may sound on paper, the only way you can truly appreciate their warmth, detail and unmatched beauty is to experience them
