Dan D’Agostino is one of the elder statesmen of the high-end audio industry.

He founded Krell Industries 1979. (The company name would ring familiar to fans of the 1956 science fiction movie Forbidden Planet).

His groundbreaking product was a high-powered solid state monoblock that rocked the audio world shibboleth that tubes were the only true path to audio nirvana.

When Dan debuted his new eponymous company at CES in 2011, with the bold design of the Momentum monoblock, it again heralded a new age of solid state innovation and originality.

Interestingly, he shared that room at CES with the speaker designer who, thirty years earlier, had used the Krell KMA-200 to introduce his first product, the Wilson Audio Modular Monitor.

In the decade plus since, the Momentum series has expanded; and—still driven to push the state of the art—Dan created the Relentless series of mono blocks, and most recently, the Relentless preamplifier.

The Progression series was initiated to bring Relentless derived technology into a less Olympian platform.

Every D’Agostino product is available in either black or silver finish, and each is hand-built in their 7200 square foot manufacturing facility in Cave Creek, AZ.
