Dan D’Agostino Progression M550 Mono Amplifier

Description

The Dan D’Agostino Progression M550 Mono Amplifier exemplifies the pinnacle of amplifier engineering, showcasing a blend of cutting-edge technology and meticulous craftsmanship. With a design philosophy rooted in uncompromising audio performance, this amplifier stands as a testament to the pursuit of sonic perfection.

Key Features:

  1. Exquisite Heat Sink Design: The Progression M550 features a heat sink design inspired by the flagship Relentless Mono Amplifier. Each heat sink is meticulously milled from a solid 48.5-pound aluminum billet slab, exhibiting exceptional cooling efficiency. This ensures that the amplifier operates reliably even at full-rated power.
  2. Potent Power Delivery: As reflected in its model name, the Progression M550 Mono Amplifier boasts impressive power output capabilities. It can deliver 550/1,100/2,220 watts into 8/4/2 ohms, providing ample power to drive a wide range of speakers.
  3. Advanced Input Topology: The Progression M550 incorporates substantial revisions to its input topology, resulting in improvements across various parameters, including distortion, signal-to-noise ratio, channel separation, and bandwidth. New transistors with significantly higher power-handling capabilities have been implemented, enhancing low-frequency performance and extending the amplifier’s bandwidth.
  4. Super Rail Topology: This innovative topology employs higher voltage rails in the sections preceding the output stage. This “boost” enables the musical signal to utilize the full capability of the output voltage rails, leading to improved dynamics, lower distortion, and a tighter grip on the speaker.
  5. Iconic Power Meters: The anodized aluminum faceplate includes the characteristic power meters synonymous with D’Agostino amplifiers. The Progression M550’s 180° meter needle is driven by a high-speed ballistic circuit, enhancing its responsiveness.
  6. Hand-Crafted Excellence: Each Progression M550 Mono Amplifier is meticulously hand-built, reflecting a commitment to craftsmanship and quality.
