Dan D'Agostino Momentum MxV Integrated Amplifier

Dan D'Agostino Momentum MxV Integrated Amplifier 

The Power of Supply

Defying its compact size, the Momentum MxV Integrated is a powerhouse amplifier. The backbone is a new ultra-quiet 2,000VA linear transformer. A unique toroidal winding technology, first employed in the Momentum M400 amplifier, delivers greater power output from a similarly sized conventional transformer keeping the Momentum MxV Integrated surprisingly small for its capability. This engine drives a nearly 60,000ⲙF capacitor bank resulting in 250/500/1,000W power output into 8/4/2Ω speaker loads. Internal circuitry filters RF noise from the AC powerline and compensates for asymmetric power waveforms and DC on the mains.

The scope of the Momentum MxV Integrated amplifier design requires the use of two separate chassis – a dedicated audio chassis and a separate power supply. The two chassis interlock through special mechanisms in the mounting feet of each chassis. Thirty pin interlocking 30-amp, gold plated connectors eliminate wiring normally used for these applications and the associated anomalies that can occur. This distinctive construction isolates the audio signal completely, both physically and electrically from the power supply section. Physical isolation offers additional room to maximize both power and audio circuitry.

Digital Streaming and Phono Module 

The final output stage features new output transistors that were originally sourced for the flagship Relentless Monoblock Amplifier. 28 high speed, high-output transistors are used in the Momentum MxV Integrated. Each transistor mounts with two stainless steel fasteners—a rarity among flat-package transistors—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 speakers. Additionally, every output transistor is measured and only devices that match the required performance specifications are included in the production of the Momentum MxV Integrated Amplifier. As with all D'Agostino models, the Momentum MxV Integrated Amplifiers feature discrete, direct-coupled balanced circuitry, the most accurate circuit platform possible. 

The optional phono module adds vinyl playback capability to the Momentum MxV Integrated Amplifier. Low output moving coil cartridges are supported with over 60dB of gain and loading options from 100Ohm-47kOhm.
