When power meets finesse — and they become best friends.
The Momentum Z Monoblock Amplifier is not just another power amp — it’s a statement. Born from over 15 years of obsessive design and engineering refinement, this latest iteration from Dan D’Agostino Master Audio Systems takes what made the original Momentum series legendary and turns it up to serious audiophile levels.
This is big-league amplification: raw muscle, but with a velvet glove. And yes, you can feel it in every waveform.
Why it matters
If you’ve ever heard a truly great monoblock, you know the feeling: sound that feels alive, instruments that breathe, bass that has authority without aggression. The Momentum Z delivers exactly that — and then some.
This amplifier doesn’t just drive speakers — it commands them.
What makes the Momentum Z special
🎚️ Revolutionary Power Architecture
At the heart of the Momentum Z is a proprietary Kinetic Drive Regulator. This isn’t marketing fluff — it’s a power supply that keeps the amp immune to mains power irregularities and speaker load craziness. That means stability you can feel in dynamics, timing, and sheer control.
Twin 1,200 VA toroidal transformers and a massive power reservoir serve up:
500 W into 8 Ω
1,000 W into 4 Ω
2,000 W into 2 Ω
Translation? It will drive even the hungriest loudspeaker with authority — no flinching, no shade.
This is the first D’Agostino power amplifier to use a JFET-based front end — giving ultra-high input impedance and extremely low noise. What that means to you: micro-details are preserved, midrange warmth is natural, and nothing gets coloured or smeared.
Smart Monitoring
For the first time on a Dan D’Agostino power amp, the Momentum Z features an Ethernet port — not for streaming music, but for real-time diagnostics. Through your browser you can monitor:
operating voltages
temperature
bias
DC offset
trigger status
and more — because powerful gear deserves insightful feedback.
Thermal & Mechanical Brilliance
Those solid copper heatsinks aren’t just pretty — copper has nearly twice the thermal conductivity of aluminum. Each is carved from a single 42 lb solid billet, machined with elliptical precision to maximize heat dissipation.
Heat management this clever means the amp stays stable, even under punishing loads.
⏱ Dual Domain Meter Display
Just because you bought an amp with serious chops doesn’t mean you can’t have a little fun watching it work.
The Momentum Z uses an elegant 3.5″ high-resolution LCD for stats, alongside the classic analog meter needle — a beautiful nod to analog tradition with modern brains.
