Overview

The Dan D’Agostino Relentless 800 Monoblock Amplifier extends the flagship Relentless series’ unparalleled performance into a more compact, yet equally formidable, package. Delivering 800 W into 8 Ω and doubling down to 3,200 W into 2 Ω, it effortlessly commands any loudspeaker. Its core is a fully complementary, discrete, and direct-coupled circuit with zero global negative feedback, ensuring absolute signal purity.

Power is supplied by a nearly 4 kW toroidal transformer and 400,000 μF of capacitance, feeding 84 high-power output transistors. An innovative copper/aluminum elliptical heatsink and a new bias stability circuit provide exceptional thermal management and extended Class A operation. Incorporating “Super Rail” technology for explosive dynamics, and housed in a meticulously machined solid aluminum chassis, the Relentless 800 offers the signature D’Agostino sound—unrivaled musicality, vast dynamics, and a strikingly lifelike soundstage—in a remarkably potent form.

Super Rails
Super Rail employs higher voltage rails in the sections prior to the output stage, effectively “turbocharging” the amplifier and exploiting the full capability of the output voltage rails—which improves dynamics, lowers distortion, and tightens the amplifiers’ electrical grip on the speaker.

The output stage features the same new transistor as in the driver section for sonic and technical consistency. Individual complementary pairs undergo our transistor matching protocol to ensure that gain linearity is virtually identical from 50mA to 5A. Additionally, every one of the 84 output transistors used is measured and only devices that match the required performance specifications are included in the production of Relentless 800 amplifiers. The high-output transistors used in the Relentless 800 are among the fastest available. These high-powered transistors mount with two stainless steel fasteners—a rarity among flat-package transistors—for maximum thermal transfer to the copper heat sinks. A capacitor/resistor network connected to the base of each transistor guarantees stability even at high frequencies and with low-impedance speakers. As with all D'Agostino models, the Relentless 800 amplifiers feature discrete, direct-coupled balanced circuitry - the most accurate circuit platform possible.

Elegantly Functional

The Relentless 800 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 makes certain that the Relentless amplifiers run 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.

The entire chassis of the Relentless 800 amplifiers are 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.
