The Dan D'Agostino Classic Stereo amplifier is a high-performance stereo power amplifier based on the design philosophy of the Momentum amplifiers but with less opulent construction. It features a circuit topology derived from the Momentum series, uses a costly 'through-hole' manufacturing technique for robust electrical connections, and employs military-grade components throughout. The amplifier delivers 300 watts per channel into 8 ohms, 600 watts into 4 ohms, and 1200 watts into 2 ohms, providing outstanding dynamic capacity and current delivery to handle complex speaker impedance curves. It offers a frequency response from 1 Hz to 200 kHz (-1 dB), balanced inputs with XLR to RCA adapters supplied, and an input impedance of 100 kohms. The unit is hand-built in the USA under Dan D'Agostino's supervision, weighs approximately 50-55 kg, and measures 483 x 292 x 508 mm (W x H x D). It is noted for its musicality, excellent imaging, and ability to drive difficult loads with ease. The Classic Stereo amplifier is discontinued and no longer manufactured.
