In 2011, Dan D'Agostino founded Dan D'Agostino Master Audio Systems, a company that would reflect his lifelong passion for excellence in audio design. His goal was to create products that would push the limits of engineering, delivering sound that was both technically precise and emotionally engaging. With his vast experience and reputation as one of the industry's foremost amplifier designers, D'Agostino aimed to redefine high-end audio, focusing on craftsmanship, innovation, and performance. The launch of his own brand allowed him to bring his vision to life without compromise.

The Momentum amplifier, released in 2011, was the first major product from Dan D'Agostino Master Audio Systems and served as a defining moment for the brand. Combining incredible power with exceptional clarity, the Momentum amplifier was designed to deliver precise, distortion-free audio across all frequencies. It incorporated advanced technologies and a unique design, including a proprietary power supply and a unique cooling system, ensuring that the amplifier could handle high power loads without compromising sound quality.

Following the success of the Momentum amplifier, Dan D'Agostino introduced the Momentum preamplifier in 2012, designed to perfectly complement the amplifier and elevate the entire audio experience. The preamplifier shared many of the same design principles as the amplifier, emphasizing precision and power handling, but it also introduced new innovations in signal processing and noise reduction. The Momentum preamplifier provided greater transparency and detail, creating a seamless connection between the source and amplification stages of the audio system.

In 2015, Dan D'Agostino Master Audio Systems launched the Progression series, offering audiophiles a slightly more accessible entry point into the world of D'Agostino’s high-end audio products. The Progression series maintained the exceptional performance and craftsmanship of the brand’s flagship products but at a more attainable price point. The series included power amplifiers and preamplifiers that delivered remarkable sound quality, with the same level of engineering excellence that had become synonymous with the D'Agostino name.

The release of the Relentless amplifiers in 2018 marked the pinnacle of Dan D'Agostino's design philosophy. These amplifiers represented a new level of power, precision, and performance, taking D'Agostino’s engineering to unprecedented heights. With an innovative dual-mono configuration and an enormous power supply, the Relentless amplifiers delivered a level of amplification that was unmatched in the industry. They were designed to handle even the most demanding speaker loads, offering total control and stability across all frequencies.

In August 2024, Dan D'Agostino introduced the Momentum C2 Preamplifier, an upgrade over the previous Momentum HD model. The Momentum C2 featured several technical enhancements, including improved isolation and a dedicated chassis designed to minimize vibration and interference. Inspired by the Relentless preamplifier, the Momentum C2 incorporated advanced technologies that further refined the preamplifier’s performance, offering even more clarity, depth, and resolution. The Momentum C2 also featured optional digital streaming capabilities through a Digital Streaming Module (DSM), allowing audiophiles to access their music from various sources while maintaining the exceptional sound quality that D'Agostino products are known for.
