Dan D'Agostino Momentum HD Preamplifier with Original Case & Remote

We are very happy to present a beautiful pre-owned D'Agostino Momentum HD Preamplifier in excellent, lightly used condition; presented with its original hardshell case and complete accessory set. The Momentum HD is widely regarded as one of the finest line-stage preamplifiers ever engineered. Designed by Dan D'Agostino himself — the visionary behind the original Krell KSA and KRS Reference series — it combines a zero-feedback, discrete Class A topology with D'Agostino's signature Swiss-watch industrial aesthetic. The result is a component that communicates music with breathtaking realism: a vast, three-dimensional soundstage, effortless dynamic authority and a purity of tone that simply cannot be replicated at any lower price point. This particular unit has lived the majority of its life in a dedicated listening room as part of a world-class reference system anchored by a Wilson Audio Chronosonic XVX loudspeaker system and fully optimized with Transparent Reference and Opus cabling. It has been driven gently, by an owner who understood exactly what they had. The sonic performance is indistinguishable from new. If you are assembling or refining a reference-caliber system and want a preamplifier that will be the last you ever need to buy, this is a rare chance to acquire one of the hobby's most celebrated components at a meaningful savings over retail, with all original packaging and accessories intact.
