DAN D’AGOSTINO PROGRESSION INTEGRATED

Housing a preamplifier and a stereo amplifier in a single chassis, an integrated amplifier removes the cost and complexity of additional interconnects and power cords. Priced at $20,000, the Progression Integrated from Dan D’Agostino Master Audio Systems combines a versatile line stage, capable of revealing the most subtle nuances of source signals, and a powerhouse amp making a formidable 200 watts-per-channel into 8 ohms—just the ticket for hungry, full-range speakers whose woofers move a lot of air, like the 801 D4 Diamonds here. Additional options include a $2,000 phono section and a $5,000 Digital Streaming Module that, taken together, make this one of the most well-equipped and robust integrated command centers available.
