Dan D'Agostino Progression Mono Amplifiers (Black)

These highly regarded monoblock amplifiers rarely become available for sale on the used market.  They have tremendous reserve and are stable down to 1-ohm and will drive any pair of speakers with authority but not at the expense of finesse and musicality.  They sound exquisite at low listening volumes but can effortlessly recreate a performance at full scale volumes.  They are in the elegant BLACK finish and are in perfect physical (no scratches or blemishes) and functional condition.  They have been used caringly in a smoke-free, pet-free, and child-free environment.
