Dan D'Agostino Momentum S250 MxV Stereo Amplifier

All the muscle of D'Agostino's monoblocks, in a single stereo chassis.

Part Time Audiophile's Mohammed Samji said it had "the most significant and profound impact on music reproduction in my room."

"The word for this gear is commanding." — Jacob Heilbrunn, The Absolute Sound

Not everyone has the room — or the desire — to run two separate monoblock amps. The S250 MxV gives you the same MxV-generation circuitry, the same Relentless-derived output devices, and the same serious power reserves as its monoblock siblings, just packaged as one compact stereo amplifier. It's the easy way into genuine high-end D'Agostino sound.

Don't mistake "compact" for "modest," though. This thing puts out 250 watts per channel into 8 ohms and simply doubles that as impedance drops, so it stays completely unbothered by demanding speaker loads. Inside, the same reworked driver and output stages found in the flagship monoblocks are at work — higher operating bias for more Class A operation, additional output transistors to spread the workload, and new copper heatsinks to keep it all running cool under pressure. The result is a sound that's authoritative and expansive but never forced.

Like the M400 MxV, this is a chassis-compatible upgrade — if you own an earlier Momentum stereo amp, D'Agostino can bring it up to full MxV performance without a full replacement.

If you want monoblock-grade command over your speakers without committing to two separate amplifiers, this is the shortcut.
