Dan D’Agostino audio systems has unveiled the Momentum Z Monoblock Amplifier, a new flagship design that marks fifteen years of this Arizona-based high-end audio brand. This latest model from the momentum range introducing; major changes to the power supply, input stage, thermal design and system monitoring. The Momentum Z is built around a new power architecture using a pair of 1,200 VA linear toroidal transformers and the company’s proprietary Kinetic Drive Regulator that is said to allow the amplifier to maintain ultra-stable voltage rails regardless of incoming AC quality or the changing electrical demands of connected loudspeakers.
Visually, the Momentum Z maintains the D’Agostino cosmetics and is available in either a silver or black finish. Its signature copper heat sinks are each machined from single 19Kg (42lb) billet, and are designed to improve airflow and heat dissipation. A new Dual Domain Meter Display combines a 3.5-inch LCD for digital status information with the brand’s iconic analog mechanical meter.
The Momentum Z produces 500 watts into 8 ohms, 1,000 watts into 4 ohms and 2,000 watts into 2 ohms. This exceptionally power monoblock design is controlled with a Kinetic Drive Regulator using a hybrid of MOSFET and bipolar devices that stabilise the amplifier against mains fluctuations and reactive speaker loads. In theory, that should deliver lower noise, reduced distortion and greater consistency when driving difficult loudspeakers.
The signal path is fully analogue, while a software-based control system monitors bias and operating conditions in real time. This latest model also introduces a new JFET-based input stage, chosen for its low noise and linear behavior when handling very small signals. Two selectable input modes allow the amplifier to be optimised for D’Agostino’s own preamplifiers or for conventional third-party designs.
The Momentum Z gains Ethernet connectivity with an integrated RJ45 port that provides access to a browser-based dashboard showing operating voltages, temperature, bias, DC offset and trigger status in real time, along with control of the front-panel display. Other rear panel connections include; 3.5mm 12VDC trigger I/O, 1 x XLR input and 1 x pair of speaker binding posts.
