D’Agostino Progression Integrated Amp w/ DAC streamer and Phonostage

  • Used

  • $20,000 – Shipping separate- With Full Warranty

  • Store Demo ONLY

  • Condition 9/10

The high sound quality of the Progression is its key merit, but anyone who is familiar with the problem some audiophiles encounter with their partners over the impact a high-end system can have on room décor know it is a real issue. Accordingly, let me begin by noting that the Progression manages to fit all its features—including two functional front-panel meters—into a unit that only measures 17.25 inches wide by 6.63 inches high by 20.13 inches deep, although the quality of its componentry is indicated by the fact that it weighs some 57 pounds.
