The Dan D'Agostino Momentum MxV Integrated Amplifier combines the front-end performance of the Momentum HD Preamplifier with the sheer power section of the Momentum MxV amplifiers into an extraordinarily elegant solution. Available through Trimira Audio, Brisbane’s premier destination for ultra-high-end audio, the Momentum MxV Integrated proves that a single-system solution can deliver true reference-grade performance.
Deriving its name from physics—where momentum equals Mass times Velocity ($M \times V$)—the Momentum MxV Integrated delivers an astounding 250 Watts per channel into 8 Ohms, 500 Watts into 4 Ohms, and 1,000 Watts into 2 Ohms, allowing it to drive virtually any loudspeaker load with complete dynamic authority.
Key Features & Engineering Innovations
-
Two-Chassis Interlocking Isolation Architecture: Physically and electrically isolates the sensitive analog circuitry from power supply noise. The audio chassis nests atop a dedicated power supply base, interconnecting via 30-pin, 30-amp gold-plated connectors to eliminate external wiring anomalies.
-
Relentless Output Stage Technology: Incorporates 28 high-speed, high-output transistors originally sourced for the flagship Relentless Monoblock, each mounted with dual stainless steel fasteners for optimal thermal transfer to the solid copper heatsinks.
-
Ultra-Quiet 2 kVA Linear Transformer: Uses specialized toroidal winding techniques paired with a nearly 60,000 µF capacitor bank, delivering explosive dynamic headroom and filtering AC powerline RF noise.
-
Modular Field-Upgradable Options: Configurable to individual listening needs with an optional Digital Streaming Module (DSM) (adding SPDIF, Optical, USB-A, RJ45 Ethernet, Wi-Fi, and 32-bit/192kHz / DSD1024 decoding via iOS DSM app) and an optional Moving Coil Phono Module (delivering over 60 dB of gain and loading options from 100 Ω to 47 kΩ).
-
50% Increase in Class A Bias: An upgraded bias-stability circuit increases Class A operation by nearly 50%, producing liquid mid-range resolution and rich, natural harmonic depth.
-
Machined Aluminum Chassis & Integrated Headphone Jack: Features a precision-milled aluminum chassis with zero visible fasteners, a signature copper Venturi cooling system, and a discrete high-drive 1/4-inch headphone output hidden behind a sliding front panel logo door.
