The Dan D’Agostino Relentless Epic 1600 Monoblock Amplifier stands as a pinnacle of audio engineering, designed for ultimate power and unyielding musical fidelity. This behemoth delivers a staggering 1,600 W into 8 Ω, doubling down to 6,400 W into 2 Ω, controlling any loudspeaker with absolute authority. Its true balanced, discrete, and direct-coupled circuitry operates without global negative feedback, maintaining impeccable linearity.

Central to its performance is a massive 5.5 kW linear power supply with 600,000 μF of capacitance, feeding over 100 high-power output transistors. An innovative elliptical copper/aluminum heatsink ensures optimal thermal management, allowing extended Class A operation. Featuring “Super Rail” technology for enhanced dynamics and housed in a meticulously machined solid aluminum chassis, the Relentless Epic 1600 represents D’Agostino’s pursuit of audio perfection, delivering a soundstage of unparalleled scale, nuance, and dynamic realism.

Perfect Balance and Absolute Power
The core of the power supply is a 5.5 KVA linear transformer that uses multiple sections running in concert, potted, and encased in a metal shield. This design reduces transformer noise to nearly zero and protects the audio circuitry from the transformer’s magnetic field. The transformer feeds a custom-designed rectifier circuit and a 600,000-microfarad/100-volt capacitor bank. A custom-made Delrin brace mechanically grounds each capacitor so they won’t vibrate. An additional electrostatic shield isolates the A slow-start circuit activates the power supply in stages, eliminating concerns about capacitive inrush tripping household circuit breakers.

Ultimate Control for Any Loudspeaker
Dan D’Agostino’s exclusive Super Rail concept makes maximum use of the incredible resources of this power supply. Super Rail employs higher voltage rails in the sections prior to the output stage, effectively “turbocharging” the amplifier. Every amplifier uses two voltage rails, a positive one and a negative one. Voltage rails support the delivery of power to the speaker. The music signal swings between these two rails but due to natural loss, the musical signal never reaches the output rails’ full capability. A Super Rail overcomes this limitation. The Super Rail employs higher voltage rails in the sections prior to the output stage. This voltage "boost" allows the musical signal to exploit the full capability of the output voltage rails. Extending the musical signal swing closer to the output rails maximizes the performance of the output circuitry design itself. This inspired technique improves dynamics, lowers distortion, and tightens the amplifier’s electrical grip on the speaker.

Strikingly Elegant
The Relentless Mono Amplifier's new power meter measures more than eight inches in diameter. The meter’s range and response automatically adjust to the level of the incoming signal, making it easy to read no matter how quiet or loud the musical passage.

The entire chassis of the Relentless Mono Amplifier is machined from solid aluminum, for superior shielding, thermal stability, and vibration damping. High-precision milling allows the entire chassis to fit together solidly with no visible fasteners. A 1 µm-deep diamond cut finish with a synthetic enamel coating completes the aesthetic.

An Amplifier Like No Other
The Relentless Mono Amplifier's unique heat sink combines copper and aluminum in a thermal engine that wicks away heat from the connected devices. The elaborate elliptical design expands on the venturi heat sink first explored in the Momentum series and assures that the Relentless Mono Amplifier runs safely and reliably even when delivering its full rated power. Thermal, short circuit, and DC protection are included in a non-invasive but comprehensive defense against any external system faults.

In keeping with the tradition begun with the Dan D’Agostino Audio Systems Momentum amplifiers, the Relentless Mono Amplifier offers a single XLR balanced input. Speaker connections are made using massive custom-made binding posts made from gold-plated brass. A special tool is included for tightening speaker cable connections without damaging the terminals themselves.

Just as no audio designer has been more relentless than Dan D’Agostino in his pursuit of perfection, we think it safe to say that no power amplifier has been designed and built to a higher standard than the Relentless Mono Amplifier.
