Dan D'Agostino Momentum M400 MXV Amplifier
At its core is a completely redesigned 2,200 VA linear transformer with a new winding scheme that cuts the hysteresis effect — the energy loss that quietly robs amplifiers of clarity and control — by 90%. Feeding that is a 100,000 μF capacitor bank, and driving it all are 28 high-output transistors originally developed for D'Agostino's $300,000 Relentless flagship. They run at 69 MHz. They are, by a wide margin, some of the fastest transistors in any amplifier at any price. The result is a frequency response that starts at 1Hz and doesn't stop until 200kHz — a full octave beyond what your ears can detect, in both directions.
The numbers are extraordinary. But the sound is the reason people buy these. Reviewers reach for words like "sumptuous," "mellifluous," and "silky" — vocabulary usually reserved for the very best tube amplifiers. Massive, controlled bass. A midrange that lets musicians sound like musicians. A treble that's refined without being polite. Every record you play will have something new in it.
