The highly acclaimed Momentum MxV Integrated Amplifier achieves a level of performance never before accomplished in an integrated amplifier. Combining the front-end technology from the Momentum C2 Preamplifier and the power section of the Momentum MxV amplifier, it delivers Momentum Series performance in a compact framework only hinting at the advanced circuitry within.
Every section of the Momentum MxV Integrated Amplifier benefits from advancements pioneered in the Relentless and Momentum Series. In the preamplifier, six left and right circuit boards make up the input, volume control, and output sections. The advantage of an integrated amplifier is the direct connection of the preamplifier output stage to the amplifier input section, eliminating connector and cable anomalies that potentially impact electrical and sonic performance. Crucial to the circuit are bipolar transistors powering the front end of the amplifier that deliver 10 times the current and power of devices previously employed.
These wider-bandwidth, higher-power components extend low- and high-frequency performance with reduced distortion. Energizing the driver stage is a 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 Monoblock amplifiers. A total of 28 high-speed, high-output transistors per channel are used, each mounted for maximum thermal transfer to the copper heat sinks. A capacitor/resistor network connected to the base of each transistor ensures stability even at high frequencies and with low-impedance loudspeakers. As with all Dan D’Agostino Master Audio Systems components, the Momentum MxV Integrated Amplifier features discrete, direct-coupled, balanced circuitry, the most accurate circuit platform possible.
