MOMENTUM MxVINTEGRATED AMPLIFIER

THE ULTIMATE INTEGRATEDThe Momentum MxV Integrated Amplifier by Dan D’Agostino Master Audio Systems achieves a level of performancenever before possible in an integrated amplifier. Combining the front-end technology from the Momentum HD
Preamplifier and the power section of the Momentum MxV amplifier, it delivers Momentum Series performance ina compact framework only hinting at the advanced circuitry within. Employing a configurable, modular design, thecore line stage section can be augmented to include a digital streaming and/or phonostage module. When fully
equipped, the Momentum MxV Integrated Amplifier topology is a seamless circuit working as one from input tooutput, optimizing performance in a way otherwise not possible.
SERIOUS POWER SUPPLY
Defying its size, the Momentum MxV Integrated Amplifier is a powerhouse. A new ultra-quiet 2,000VA linear
transformer with unique toroidal winding technology, first used in the Momentum M400 Mono Amplifier, delivers
greater power output than a conventional transformer. This engine drives a nearly 60,000 µF capacitor bankresulting in 250/500/1,000 watts of power output into 8/4/2Ω speaker loads. Internal circuitry filters RF noisefrom the AC powerline and compensates for asymmetric power waveforms and DC on the mains. Isolating theaudio signal physically and electrically from the power supply section requires two separate chassis that elegantlyinterlock through 30-pin, 30-amp, gold-plated connectors.
ADVANCED AUDIO CIRCUITRY
Every section of the Momentum MxV Integrated Amplifier benefits from advancements pioneered in the Relentlessand Momentum Series. In the preamplifier, six left and right circuit boards make up the input, volume control, andoutput sections. The advantage of an integrated amplifier is the direct connection of the preamplifier amplifier stage
to the amplifier input section, eliminating connector and cable anomalies that potentially impact electrical andsonic performance. Crucial to the new circuit are the new bipolar transistors powering the front end of the amplifierthat deliver 10 times the current and power of devices previously employed. These wider-bandwidth, higher-powercomponents extend low- and high-frequency performance with reduced distortion. Energizing the driver stage isa new bias stability circuit providing a nearly 50% increase in operating bias. Increasing Class A operation directly
correlates to better sound quality. A unique copper aluminum thermal engine heatsink and new bias scheme prevent

excessive temperatures even under the greatest demand. Additional power transistors in the output stage reduce
workload for each device, minimizing stress and allowing the entire output section to work more efficiently. The final
output stage features new output transistors sourced for the Relentless Mono Amplifiers. A total of 28 high-speed,
high-output transistors are used, each mounted with two stainless steel fasteners—a rarity among ﬂat-packagetransistors—for maximum thermal transfer to the copper heat sinks. A capacitor/resistor network connected tothe base of each transistor ensures stability even at high frequencies and with low-impedance speakers. As withall Dan D’Agostino Master Audio Systems components, the Momentum MxV Integrated Amplifier features discrete,
direct-coupled, balanced circuitry, the most accurate circuit platform possible.
DIGITAL STREAMING AND PHONOSTAGE MODULES
An optional digital streaming module vaults the Momentum MxV Integrated Amplifier to the cutting edge of today’s
digital listening environment, adding connectivity for legacy sources and premier streaming functionality. Fieldupgradable, the digital module adds SPDIF coaxial, Optical, and USB-A for legacy digital components and Ethernetand Wi-Fi for network-based music. The iOS D’Agostino DSM App provides built-in Tidal, Qobuz, and MQA decoding,plus complete unit control. PCM signals up to 32 bit/192 kHz and DSD signals up to DSD1024 are supported. An
optional phonostage module for MM and MC cartridges supports low-output moving-coil cartridges with over 60 dBof gain and loading options from 100Ω–47kΩ.
Both chassis of the Momentum MxV Integrated Amplifier are machined from solid aluminum for superior shielding,thermal stability, and vibration damping. High-precision milling allows the casework to fit together with no visible
fasteners. Each unit is hand-built and individually tested in D’Agostino’s Arizona factory by our team of technicians
and craftsmen.
