Dan D'Agostino Momentum Z Monaural Amplifier (sold as a pair)

A new benchmark for what "immune to interference" actually means.

A new benchmark for what "immune to interference" actually means.

Most amplifiers quietly compromise under real-world conditions — mains power isn't perfectly clean, and your speakers push back against the amp in ways that subtly shift its behavior. The Momentum Z was built specifically to stop caring about either problem. Its proprietary Kinetic Drive Regulator locks the amp's internal voltage rails rock-steady regardless of what's happening on your AC line or how your speakers are behaving, so the current reaching your speakers stays clean and consistent no matter what the music throws at it.

It's also the first D'Agostino amplifier to use a JFET-based input stage — a technology chosen for its ultra-low noise and ultra-high input impedance, meaning the delicate details in the signal survive the trip into the amp fully intact. Feed that into dual 1,200 VA transformers, a switchable input for use with D'Agostino or third-party preamps, and massive 5-axis-machined copper heatsinks that keep everything running cool at full output, and you get an amplifier engineered to simply not be the limiting factor in a system, ever.

Launched for D'Agostino's 15th anniversary, the Momentum Z is a genuine new platform — right down to being the company's first power amp with an Ethernet port, letting you monitor voltage, temperature, and bias in real time from any browser on your network.
