Dan D’Agostino - Relentless Epic 1600 - Monoaural Amplifier

The Dan D’Agostino Relentless Epic 1600 Monaural Amplifier represents the ultimate evolution of the company’s flagship amplifier platform, engineered without practical limitation to achieve extraordinary power delivery, transparency, and loudspeaker control. Incorporating extensive circuit refinements and upgraded component technologies, the Relentless Epic 1600 establishes a new reference standard for high-current monoblock amplification.

Every major amplifier section — including the power supply, input, driver, and output stages — has been comprehensively redesigned for the Epic generation. A massive 5.5kVA linear transformer working alongside a 600,000μF capacitor bank provides virtually limitless current reserves, while new wide-bandwidth input devices, enhanced driver circuitry, and current-domain gain stages dramatically improve transient precision, low-level resolution, and overall dynamic realism.

The Relentless Epic 1600 also utilizes Dan D’Agostino’s advanced copper and aluminum venturi-style thermal management system, allowing expanded Class A operation and exceptional long-term stability under extreme demand. Housed in a precision-machined solid aluminum chassis with the company’s signature oversized analog power meter, the Relentless Epic 1600 stands among the most ambitious and uncompromising audio amplifiers ever created.
