The Dan D’Agostino Progression S350 Stereo Amplifier delivers a potent blend of power and musicality, providing exceptional control over any loudspeaker. Outputting 350 W per channel into 8 Ω, and doubling down to an impressive 1,400 W into 2 Ω, this amplifier is built on a foundation of a massive 2,000 VA power supply and nearly 100,000 μF of capacitance.

Its fully balanced, complementary, discrete circuitry is enhanced by 48 high-power output transistors, derived from the flagship Relentless series. The innovative “Super Rail” technology boosts voltage prior to the output stage, maximizing dynamics and lowering distortion for an incredibly engaging sound. Efficient elliptical heatsinks, milled from solid aluminum, ensure optimal thermal performance and extended Class A operation. Housed in an elegant anodized aluminum chassis with a distinctive power meter, the Progression S350 offers a remarkably dynamic, transparent, and tonally accurate performance, empowering loudspeakers to achieve their full sonic potential.

Substantial Foundation
Abundant power is required for realistic sound quality and is a cornerstone of Dan D’Agostino Master Audio Systems’ amplifier design. The Progression Stereo continues this practice. A graceful anodized Aluminum chassis houses a 2,000 VA power supply transformer coupled to nearly 100,000 microfarads of power supply storage capacitance. Paired to this foundation is a fully complementary driver stage, and output circuitry outfitted with 48 power transistors - 24 each for the left and right channels generating an imposing output. Initially used in the Relentless Mono, the output power device provides the foundation for an upgraded output stage. This transistor extends high frequency response, increases power handling 50%, and features tighter tolerance gain matching between complementary NPN/PNP pairs.

A wider safe operating area and superior gain linearity provides greater thermal stability throughout the amplifiers’ power delivery. Coupling the new output device to the high efficiency heat sink design affords an increase in operating bias. Higher operating bias lowers crossover distortion improving instrument timbre and tonal reproduction. The Progression Stereo delivers 350 Watts into 8 Ohms and delivers 700 Watts into 4 Ohms, and properly doubles its output again into 2 Ohms, with a 1,400 Watt power output. The essence of live music, dynamic contrasts, are faithfully reproduced with leading edge transients spectacularly depicted.

Elegantly Powerful
Inspired by the elegant faces of classic Swiss watches, the Progression S350 Stereo is fronted by an exposed movement power meter. Featuring two 90° needle swing arms, a high-speed ballistic circuit enhances the meter’s responsiveness. Longer swing arms improve readability across the amplifier’s entire output range.

Drawn directly from the Relentless Mono Amplifier, each heatsink is milled from a single, 48.5-pound (22-kilogram) aluminum billet slab. This highly efficient elliptical form dramatically improves the cooling ability of the design and assures that the Progression S350 Stereo Amplifier runs safely and reliably even when delivering its full-rated power. Standard finishes include silver and black with custom painted finishes available on request.

Combining innovative circuitry and significant power, the Progression S350 Stereo amplifier provides loudspeakers the control element they need to achieve their full design expression.
