D'Agostino Progression S350 Stereo Power Amplifier — Silver
The Progression series is where Dan's design philosophy became most accessible without compromising what matters. The S350 puts out 350 watts per channel into 8 ohms, 700 into 4. High-bias Class A/AB operation: the amp runs warm, the bias is set high, and the transition out of Class A happens well above the power levels most program material ever demands.
The chassis is machined aluminum with D'Agostino's signature copper and aluminum aesthetic — the same design language as the Momentum series, scaled to the Progression tier. The analog meter on the face is functional, not decorative: it reads output power in real time. Balanced XLR and single-ended RCA inputs.
The silver finish is one of the cleaner looks in high-end audio — the kind of amplifier that earns its position on the rack before you ever turn it on. Once you do, the S350 is the argument for why Dan D'Agostino still matters: high-current delivery, grip on difficult loads, and a presentation that doesn't editorialize.
