New from Dan D’Agostino Grasp Audio Methods is the Momentum MxV Built-in Amplifier, which the producer claims achieves a stage of efficiency “by no means earlier than potential in an built-in amplifier”.
Combining the front-end know-how from the Momentum HD Preamplifier and the facility part of the Momentum S250 MxV Stereo Amplifier, it delivers Momentum Sequence efficiency in a compact framework solely hinting on the superior circuitry inside.
Using a configurable, modular design, the core line stage part might be augmented to incorporate a digital streaming and/or a phono stage module.
Benefiting from in depth improvement beforehand utilized to the Momentum Sequence separate elements, the Momentum MxV Built-in Amplifier executes on the potential that an built-in answer gives.
The Momentum MxV built-in Amplifier is a modular design that’s configurable to a listener’s preferences. The core line stage preamplifier part might be augmented to incorporate a digital streaming and/or a phono stage module. When totally outfitted, the Momentum MxV Built-in Amplifier topology is a seamless circuit working as one from enter to output. Every inner part is very specialised however understanding the precise complement of energy provide, management, and audio circuitry getting used collectively, affords engineering a imaginative and prescient of the system that’s usually not potential.
“Our engineering group has taken the inherent advantages of an built-in design and elevated it to a brand new stage of sonic efficiency,” says Invoice McKiegan, President of Dan D’Agostino Grasp Audio Methods. “We’ve integrated key circuitry components from the Momentum HD Preamplifier, Momentum MxV Stereo Amplifier, and Relentless fashions leading to a listening expertise that actually units a brand new normal for built-in amplifier sound high quality.”
The spine is a brand new ultra-quiet 2,000VA linear transformer. Surprisingly small for its functionality, this engine drives an almost 60,000ⲙF capacitor financial institution leading to 250/500/1,000W energy output into 8/4/2Ω speaker hundreds. Inner circuitry filters RF noise from the AC powerline and compensates for uneven energy waveforms and DC on the mains.
The scope of the Momentum MxV Built-in Amplifier design requires the usage of two separate chassis – a devoted audio chassis and a separate energy provide. The 2 chassis interlock by particular mechanisms within the mounting ft of every chassis.
A complete of 30 pin interlocking 30-amp, gold plated connectors eradicate wiring usually used for these functions and the related anomalies that may happen. This building isolates the audio sign utterly, each bodily and electrically from the facility provide part. Bodily isolation gives extra room to maximise each energy and audio circuitry.
Six particular person left and proper circuit boards make up the enter, quantity management and output sections. The core topologies have been appropriated from the Momentum HD Preamplifier together with an revolutionary FET-based enter stage.
The distinct benefit of an built-in amplifier is the direct connection of the preamplifier stage to the amplifier enter part. This pure path eliminates connector and cable anomalies that doubtlessly influence electrical and sonic efficiency. Vital to the brand new circuit are the bipolar transistors powering the entrance finish of the amplifier – these wider bandwidth, greater energy elements prolong high and low frequency efficiency with diminished distortion in each frequency extremes. Energising the motive force stage is a brand new bias stability circuit offering an nearly 50% improve in working bias.
With the brand new MxV circuit topology and our distinctive Copper/Aluminum thermal engine heatsink, warmth points should not a sensible concern within the Momentum MxV Built-in Amplifier.
The brand new bias scheme ensures bias consistency, stopping extreme temperatures even underneath the best demand. Extra energy transistors within the output stage cut back the workload for every particular person gadget, making certain your entire output part works extra effectively.
The ultimate output stage options new output transistors that had been initially sourced for the flagship Relentless Monoblock Amplifier. A complete of 28 excessive pace, high-output transistors are used within the Momentum MxV Built-in Amplifier, with every transistor mounted on to the copper warmth sinks.
A capacitor/resistor community related to the bottom of every transistor ensures stability even at excessive frequencies and with low-impedance audio system. Moreover, each output transistor is measured and solely gadgets that match the required efficiency specs are included within the manufacturing of the Momentum MxV Built-in Amplifier.
As with all D’Agostino fashions, the Momentum MxV Built-in Amplifier options discrete, direct-coupled balanced circuitry, essentially the most correct circuit platform potential.
An non-obligatory digital module provides connectivity for legacy sources, each supply and host USB performance, and premier streaming performance. Discipline upgradeable, the digital module provides S/PDIF coaxial, optical and USB-A for legacy digital elements and Ethernet and Wi-Fi for network-based music.
A devoted iOS D’Agostino DSM app gives built-in Tidal, Qobuz, MQA decoding, plus full unit management. PCM alerts as much as 32-bit/192kHz and DSD as much as DSD1024 are supported.
The non-obligatory phono module provides vinyl playback functionality to the Momentum MxV Built-in Amplifier. Low output transferring coil cartridges are supported with over 60dB of achieve and loading choices from 100-47k.
Obtainable in silver, black, or customized painted finishes, each Momentum MxV Built-in Amplifier is hand-built and individually examined in D’Agostino’s Arizona manufacturing unit.
The UK RRP is £73,998 inc. VAT, whereas the digital and phono modules add £11,398 and £5,698 to the worth, respectively.
As with all Dan D’Agostino Grasp Audio Methods merchandise, the Momentum MxV Built-in Amplifier is dropped at the UK by Absolute Sounds.
