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*Stock photos shown \u003c\/div\u003e","brand":"Dan D'Agostino","offers":[{"title":"Default Title","offer_id":54865417765155,"sku":null,"price":27500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0027\/9075\/files\/Alexia2_eabb4c45-c3bb-4503-b7ea-b7c98d431a56.png?v=1774452783","url":"https:\/\/www.definitive.com\/products\/pre-owned-dan-dagostino-momentum-m400-mxv-amplifier","provider":"Definitive Audio","version":"1.0","type":"link"}
