Dan D'Agostino Progression Neo Stereo Power Amplifier

The Progression Neo Stereo Amplifier shares its chassis, its transformer, its capacitance bank, and its circuit architecture with the Monoblock. The difference is configuration, not ambition. Where the Monoblock dedicates every resource to a single channel, the Stereo routes that same engineering across two — specified at 250 watts per channel into 8 ohms, rising to 500 watts into 4 ohms and 1,000 watts per channel into lower impedance loads.

The circuit foundation is unchanged: a JFET input stage derived from D'Agostino's Momentum Z platform, independently regulated, fully complementary and precision-balanced throughout. The 1,800 VA toroidal transformer and 96,000 microfarads of capacitance are identical to the Monoblock. Current delivery is not a compromise here — it is a choice, suited for systems where a single chassis is the right solution and the loudspeakers are capable partners.

Both balanced XLR inputs feed independent, fully balanced signal paths. A high-resolution LCD display with D'Agostino's signature power meter handles metering and diagnostics. RJ45 Ethernet provides browser-based access to real-time operating data across the home network. The Progression Neo Stereo is the entry point into the Neo platform for those who want everything the series offers in a single box.
