The Relentless Mono Amplifier is the result of an all-out pursuit to design an amplifier without limits. Incorporating elements of the Momentum series, breakthrough circuit topologies, and a new power transistor, the Relentless Mono Amplifier maintains its harmonic integrity, dynamic structure, and dimensional soundstage from its first watt to the more than 11,000 watts it is capable of delivering into a 1ohm load. With its practically unlimited power, the Relentless Mono Amplifier will drive any loudspeaker to its fullest potential, from a mere whisper to thundering dynamics.
Requiring three separate chassis to execute – The Relentless Preamplifier is the ultimate in preamplifier performance. A dedicated audio chassis for each channel and a separate power supply house our most advanced circuitry in an elegantly refined architecture.
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, energized with a new organization 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.
