RELENTLESS
D’Agostino Relentless 800 Monoblock Amplifier in Silver
Relentless 800 Amplifier
Dan D’Agostino has always had a relentless desire to better his own creations, no matter how flawless they may seem. The Relentless Epic 1600 and 800 Monoblock Amplifiers are the latest manifestation of that passion, the result of Dan’s desire for an amplifier that maintains its harmonic integrity and expansive soundstage from 0 watts to 1,600 watts. The Relentless Epic amplifiers are so powerful they can drive any speaker to its best possible performance.
We display the Relentless 800 monoblock amplifiers, paired with the Relentless Pre-Amplifier.
D’Agostino Relentless Dual-Monoblock Pre-Amplifier in Silver
Relentless Pre-Amplifier
The new Relentless Preamplifier is the ultimate in preamplifier design. The preamplifier plays a critical role in musical playback; the point in the reproduction stage when the music signal is particularly susceptible to compromise through noise and distortion. The use of three separate chassis in the design of the Relentless Preamplifier — a dedicated audio chassis for each channel separated by a power supply/control section — addresses these challenges and brings other benefits as well.
We display the Relentless Pre-Amplifier paired with the Relentless 800 amplifiers.

MOMENTUM Z
Dan D'Agostino Master Audio Systems has always pursued perfection with relentless commitment, and the Momentum Z is the latest expression of that pursuit. Introduced to celebrate the company's fifteenth anniversary, the Momentum Z represents a ground-up reimagining of every element of the legendary Momentum platform: input topology, output stage design, thermal management, power delivery, and control architecture.
Most significantly, the Momentum Z is the first D'Agostino amplifier to employ a JFET-based input stage — a device chosen for its ultra-high input impedance, exceptionally low noise, and smooth, natural transfer characteristic. The result is an immediately audible sense of quietness, openness, and midrange presence that elevates the amplifier's already extraordinary performance to an entirely new level.
At the heart of the Momentum Z is Dan D'Agostino's proprietary Kinetic Drive Regulator — a power supply technology that renders the amplifier immune to AC mains irregularities and the speaker interaction problems that commonly degrade conventional amplifier designs. Combined with newly-designed copper heatsinks, the Momentum Z maintains perfect thermal and sonic stability under any load, at any power level.
The signature Dual Domain Meter Display — a first for the Momentum line — combines an analog meter wand (true to D'Agostino tradition) with a 3.5-inch high-resolution LCD that displays real-time power data and system status. Internet connectivity via RJ45 Ethernet allows owners to monitor operating parameters — voltages, temperature, bias, DC offset — from any browser on the home network.
We display the Momentum Z monoblock amplifiers as the pinnacle of our D'Agostino Momentum demonstration system.
D’Agostino Momentum M400 MxV Monoblock Amplifier in Silver
MOMENTUM M400 MxV
The Momentum amplifier helped launch Dan D'Agostino Master Audio Systems and delivered magnificently on the initial design goals of formidable power and incomparable finesse from a compact chassis. After the initial success of the original Momentum M300 amplifier, Chief Engineer and Designer Dan D'Agostino started an engineering exercise that resulted in exciting new breakthroughs. This research led to the substantial improvements included in the new Momentum M400 MxV Monoblock Amplifier: more power, more control. The result is a sound that is more authoritative, richer, and more expansive.
D’Agostino Momentum S250 MxV Stereo Amplifier in Silver
MOMENTUM S250 MxV
The Momentum S250 MxV Stereo Amplifier delivers the extraordinary sound quality of the Momentum M400 monoblock in a more affordable stereo design. The circuit topology and construction of the stereo amplifier mirror those of the monoblock, using the same ultra-efficient copper heat sinks with venturi cooling, the same 1% metal-film resistors, the same 69 MHz output transistors and the same fully complementary balanced configuration. The result is audio fidelity equaled by no other amplifier—except, of course, the Momentum M400 MxV monoblock itself—and an efficient design that consumes less than 1 watt of power at standby.
D’Agostino Momentum C2 Pre-Amplifier in Silver
MOMENTUM C2 / C2Z PREAMPLIFIER
Building on the legacy of the Momentum HD Preamplifier, the Momentum C2 topology utilizes a revolutionary array of four transistors in a complementary, differential, push-pull arrangement, dramatically increasing input impedance and reducing noise. This unique input stage circuitry sets a new standard for performance and precision, delivering unparalleled clarity and fidelity to your audio experience. Utmost attention to design detail ensures optimal mechanical and electrical isolation, guaranteeing pristine signal integrity throughout the critical preamplification stage.
The Momentum C2Z Preamplifer is a new variant, designed with the new ultra-low impedance “Z” circuit for highest performance when used with the Momentum Z monaural amplifiers.
D’Agostino Momentum Phonostage Preamplifier
MOMENTUM PHONOSTAGE PREAMPLIFIER
Locked inside the grooves of every vinyl record is the most realistic, most natural, most moving sound one could ever experience. The trick is getting that sound off the record and into your speakers. Dan D’Agostino always found this task challenging … yet irresistible. He knew that no matter how much care he took in the design of his phono preamps, there was always more soul lurking within those grooves. With the Momentum Phonostage, he has finally extracted every last bit of music hidden in even the most microscopic fluctuations in the finest vinyl records.
D’Agostino Momentum MxV Integrated Amplifier in Silver
MOMENTUM MxV INTEGRATED AMPLIFIER
Until now, choosing an integrated amplifier always meant choosing compromise. But that's because until now, no integrated amplifier has ever borne the signature of Dan D'Agostino. The new Momentum MxV Integrated Amplifier combines the core audio circuits of the Momentum HD Pre-Amplifier and the Momentum MxV Stereo Amplifier, both of which have been acclaimed by respected reviewers around the world as among the best audio components ever created.

PENDULUM INTEGRATED AMPLIFIER
Until now, the idea of a D'Agostino integrated amplifier came with an implicit ceiling: the extraordinary Momentum MxV Integrated, one of the finest components of its kind. The new Pendulum Integrated Amplifier doesn't replace that ceiling — it adds an entirely new tier, bringing Dan D'Agostino's engineering and aesthetic philosophy to a broader audience without compromise.
At its core, the Pendulum employs the same JFET input circuit topology derived from the Momentum C2 Preamplifier, ensuring a natural, low-noise foundation that preserves every nuance of the music signal.
Connectivity is equally thoughtful: one single-ended RCA input, three balanced XLR inputs (one with theater pass-through), and balanced preamplifier outputs for seamless subwoofer integration. An optional moving-coil phono module accommodates the most discerning vinyl enthusiasts. For those who want to go further into the digital domain, the Pendulum can be optionally equipped with optical, RJ45, and Wi-Fi network connections — and it is the first D'Agostino component to include HDMI with eARC, making integration with a home entertainment system simple.
The Pendulum's LCD display — inspired by the Swiss watch aesthetic that runs throughout the D'Agostino product line — provides real-time status, metadata, and system information with a refined elegance that matches its sonic ambitions. The Pendulum is the gateway to serious D'Agostino sound.
