{"product_id":"dan-dagostino-momentum-m400-mxv-amplifier","title":"Dan D'Agostino Momentum M400 MXV Amplifier ","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eStock Photos\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e This item is currently located at Definitive in Bellevue, WA — not at the Portland shop.
