Dan D'Agostino Pre-owned S250 MXV Stereo Amplifier
The Momentum S250MXV is Dan D’Agostino’s definitive statement in a two-channel stereo chassis. 250 watts per channel, fully balanced differential circuit from input to output, and a bias stabilization system that keeps the amplifier running at a consistent operating point regardless of temperature or load. The copper meter on the front isn’t decoration — it’s a thermal management system, the same material used in the heatsink fins that line both sides of the chassis.
The MXV designation marks the most refined iteration of the Momentum stereo circuit — improved input topology, lower noise floor, and a more controlled high-frequency presentation than earlier revisions. If you’ve heard the Momentum before and wondered whether the updates were meaningful, they were.
This example is finished in silver, sourced from a Definitive client who upgraded to the monoblock configuration. It has been inspected by our team and presents in excellent condition.
