The Story

The Momentum Z celebrates D'Agostino's 15th anniversary with the most advanced Momentum amplifier ever. The headline is the copper heatsink — machined on 5 axes from a single 42-pound copper billet into the dramatic Venturi shape that has become D'Agostino's visual signature.

But the real breakthroughs are inside. A new JFET-based ultra-low noise input stage, the proprietary Kinetic Drive Regulator for power supply management, and dual 1,200VA transformers deliver 500 watts into 8 ohms with extraordinary refinement.

The Momentum Z is the first D'Agostino amplifier with Ethernet connectivity, allowing owners to monitor operating parameters in real time. The new Dual Domain Hybrid display meter combines the analog beauty of the Ballistic Meter with digital precision.

At $62,500 each ($125,000 for a pair), the Momentum Z sits between the proven M400 MxV and the flagship Relentless — offering a significant step up in power, resolution, and refinement.
