Released in celebration of Dan D'Agostino's 15th anniversary, the Momentum Z Monaural Amplifier marks a historic evolutionary leap for the iconic Momentum series. Available through Trimira Audio, Brisbane's authority in ultra-high-end audio, the Momentum Z replaces the M400 MxV with groundbreaking circuit innovations, real-time software monitoring, and an all-new power regulation architecture.
Delivering a continuous 500 Watts into 8 Ohms, 1,000 Watts into 4 Ohms, and 2,000 Watts into 2 Ohms, the Momentum Z combines effortless current drive with vanishingly low noise and silky micro-detail to command any loudspeaker in existence.
Key Features & Technological Innovations
-
Kinetic Drive Regulation: A revolutionary power supply technology paired with dual 1,200VA toroidal transformers that isolates voltage rails from AC line variations and speaker back-EMF, providing ripple-free DC power under maximum demand.
-
First-Ever JFET Input Stage: Introduces ultra-high input impedance JFETs at the critical initial gain stage, dropping the noise floor to near zero while preserving micro-spatial cues, natural vocal warmth, and harmonic depth.
-
Dual Impedance Input Mode: Features a selectable input impedance switch (1 MΩ Standard setting / 300 Ω Z-Input setting) engineered specifically to create perfect impedance matching when paired with D'Agostino Z-Series preamplifiers.
-
5-Axis Machined Copper Heatsinks: Each side features heatsinks sculpted from a single 42 lb (19 kg) slab of solid copper billet, providing nearly double the thermal conductivity of aluminum for absolute thermal and sonic stability.
-
Dual Domain LCD Meter Display: Combines traditional Swiss watch aesthetics with modern digital precision, embedding a classic analog meter wand inside a high-resolution 3.5-inch LCD readout.
-
Ethernet Real-Time Network Monitoring: Integrated RJ45 Ethernet connection allows real-time diagnostics—including rail voltages, bias current, operating temperature, and DC offset—accessible through any web browser.
