Our Thoughts RADAR AI

At US$18,995, this is fair-to-strong money for a Momentum Stereo if it’s clean and functioning properly. The original MSRP was about US$29,000–US$31,500, and the used market evidence I can see puts examples around US$14,400 on the low end and roughly US$12,950 for another second-hand listing, though those are overseas asks and don’t fully capture U.S. scarcity or condition differences. On that basis, this listing is not a bargain-basement steal, but it does sit in a reasonable zone for a luxury amp of this class.

The appeal is straightforward: the Momentum line is one of Dan D’Agostino’s most respected designs, known for grip, scale, and a very refined, authoritative presentation that works especially well with difficult speakers. A well-kept example can be a lifetime piece, and original packaging, documented service history, and known ownership would add real value here. If the unit is truly excellent cosmetically and electrically, this looks like a solid enthusiast buy rather than a risky one.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Dan D'Agostino

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.
