MODULAR DAN D’AGOSTINO MOMENTUM MXV INTEGRATED AMPLIFIER LAUNCHED

Dan D’Agostino Master Audio Systems has unveiled its second-generation Momentum Integrated Amplifier, known as the Momentum MxV.

The integrated amplifier combines technology from the Momentum HD Preamplifier and the power section of the Momentum S250 MxV Stereo Amplifier.

DAN D’AGOSTINO MOMENTUM MXV INTEGRATED AMPLIFIER

The Dan D’Agostino Momentum MxV amplifier is designed with a configurable, modular structure that allows users to augment the core line stage with optional digital streaming and/or a phono stage module. When fully equipped, the amplifier functions as “a seamless circuit, optimizing performance in a unique way”.

The Momentum MxV Integrated Amplifier has a 2,000VA linear transformer and a toroidal winding technology, delivering 250/500/1,000W power output into 8/4/2Ω speaker loads. The internal circuitry filters RF noise and compensates for powerline asymmetries and DC issues.

TWO CHASSIS DESIGN

To accommodate its design, the Dan D’Agostino Momentum MxV Integrated Amplifier requires two separate chassis, a dedicated audio chassis and a power supply. These chassis interlock through special mechanisms, using 30-pin interlocking connectors to eliminate wiring and isolate the audio signal physically and electrically from the power supply section.

PREAMPLIFIER SECTION

The amplifier’s audio circuitry has been influenced by advancements in the Relentless and Momentum MxV series models. The preamplifier section comprises six individual left and right circuit boards, borrowing core topologies from the Momentum HD Preamplifier. The integrated design allows for a direct connection of the preamplifier stage to the amplifier input section, eliminating connector and cable anomalies.

HEATSINKS

The Momentum MxV features a robust power supply, a unique Copper/Aluminium thermal engine heatsink, and a bias stability circuit for enhanced operating performance. The final output stage incorporates new transistors originally sourced for the flagship Relentless Monoblock Amplifier, designed to ensure stability even at high frequencies and with low-impedance speakers.

DAN D’AGOSTINO MOMENTUM MXV OPTIONAL MODULES

Optional modules are available, with a digital module providing connectivity for legacy sources and premier streaming functionality. The phono module adds vinyl playback capability with support for low output moving coil cartridges.
