Dan D'Agostino
Where art meets amplification.
Dan D'Agostino doesn't just design amplifiers — he sculpts them. Drawing inspiration from Swiss watchmaking and fine automotive engineering, every D'Agostino component is a fusion of extraordinary sonic performance and industrial art. The signature copper heat sinks, the Breguet-inspired power meters, the precision-machined chassis — each detail serves both form and function.
Founded in 2009 by the legendary audio engineer behind Krell Industries, Dan D'Agostino Master Audio Systems builds every component by hand at their facility in Cave Creek, Arizona. From the accessible Pendulum integrated to the awe-inspiring Relentless monoblocks, D'Agostino amplifiers deliver power with a grace and musicality that is uniquely their own.
AudioConcepts carries the full D'Agostino range — from the Pendulum through the flagship Relentless. We pair D'Agostino electronics with Wilson Audio, Sonus faber, and other world-class loudspeakers in our demonstration rooms, so you can hear what this level of amplification does for the speakers you're considering.
Relentless Mono
An all-out assault on the amplifier category. 1,600 watts into 8 ohms — doubling into 4 and 2 — with a refinement and delicacy at low volumes that belies its massive power reserves. Dual power supplies, fully balanced topology, and a chassis machined from solid aluminum and copper.

Relentless Preamplifier
The preamplifier designed to anchor the Relentless system. Three-chassis, dual-mono construction with an outboard power supply — the transparency and control necessary to let the Relentless Monoblocks perform at their absolute peak.

Momentum Z Mono
The newest Momentum — 500 watts into 8 ohms with dual 1,200VA transformers, 3D-machined copper Venturi heatsinks from a single 42-pound billet, JFET ultra-low noise input stage, and the first D'Agostino amplifier with Ethernet monitoring.

Momentum M400 MxV
400 watts into 8 ohms with immense current reserves. The MxV generation brings refinements to the power supply and signal path that further reduce noise and improve dynamic contrast. A proven reference-grade amplifier.

Momentum S250 MxV
250 watts per channel with the same fully balanced, high-current topology as the M400 — an ideal choice when space or budget favors a stereo configuration without compromising the Momentum sound.

Momentum C2 / C2Z
A revolutionary complementary four-JFET input stage in a differential push-pull arrangement. Discrete tone controls, concealed headphone amplifier, OLED status display, and optional digital streaming module. The sonic anchor for any Momentum system.

Progression M550
550 watts into 8 ohms with Momentum-derived circuit design in a more accessible package. Serious power and current capability, bringing much of the Momentum's sonic character to a broader audience.
Progression S350
350 watts per channel of high-performance stereo amplification. D'Agostino performance with a smaller footprint for systems where monoblocks aren't practical.
Progression Preamplifier
A fully balanced preamplifier with separate power supply, optional digital streaming module, Bluetooth remote, and D'Agostino's signature meter and sculpted aesthetic.
