Overview
The Dan D’Agostino Momentum HD Preamplifier uses trickle down technology from the Relentless preamp.
It is a fully discrete, balanced line-stage design with a zero-feedback signal path. A discrete differential FET input stage uses two current sources per leg, electrically isolating the input stage from external circuit variables.
The power supply separates the audio and control circuits, and is housed in a separate chassis to isolate it from the audio circuitry.
Volume control uses a precision resistor network governed by an optical controller. The optical control system does not place the controller itself in the audio signal path; the control circuitry selects different resistor values to set attenuation.
A home theatre throughput (bypass) means that the preamp can integrate easily with a home theatre system.
The Bluetooth remote eliminates the limitations of conventional infrared control.

Dan D’Agostino Master Audio Systems is a U.S. high-end audio brand founded in 2011 and based in Cave Creek, Arizona. It was created by Dan D’Agostino, one of the most influential names in modern American amplification and the longtime founder of Krell. The brand grew out of his decades of work in high-performance audio, with a clear emphasis on combining serious engineering, distinctive industrial design, and a deeply music-first philosophy.
The company is best known for amplification: flagship integrated amplifiers, power amplifiers, and preamplifiers are its core products, alongside phono stages and DACs in some lines. Its components are built for serious two-channel systems rather than broad consumer audio, and the lineup is organized around a few highly refined families rather than a wide mass-market catalog. Dan D’Agostino does not focus on speakers, turntables, headphones, or cables as its main identity.
In the market, Dan D’Agostino sits firmly in the ultra-high-end, boutique category. It is a statement brand associated with audiophile reference systems, luxury cabinetry, and very high performance expectations. Buyers tend to see it as a prestige manufacturer with strong engineering credibility and a distinctive visual signature, aimed at enthusiasts who want no-compromise amplification at the top end of the market.
