Dan D’Agostino Master Audio Systems

THE PIONEER OF HIGH-END, HIGH-POWERED AUDIO AMPLIFICATION

 
 
ABOUT DAN D'AGOSTINO

No name is more closely associated with high-end audio amplifiers than that of Dan D’Agostino. During his career of more than 30 years, D’Agostino pioneered countless advances in the design of amplifiers, preamplifiers, CD players, and surround-sound processors. He is known as the audio industry’s most passionate promoter of highquality, high-powered amplification. Makers of the world’s finest loudspeakers rely on D’Agostino-designed amplifiers for their most important demonstrations.

Progression Preamplifier

The Progression Preamplifier adds new features previously not included in a D’Agostino preamplifier. Most noticeably, the Progression Preamplifier features an optional digital module. The digital module adds coaxial, Toslink, and USB capability to the analog base model. A fully differential DAC handles PCM signals up to 24 bit/384 KHz and DSD signals up to 4xDSD (11.2 MHz). This digital module feeds a discrete, fully complementary and balanced analog signal path from input to output. Negative feedback is not used anywhere in the Progression Preamplifier, nor is it necessary. Open-loop distortion is less than < 0.006% and the open loop bandwidth extends to over 100KHz.

Progression Stereo Amplifier 

The Progression Stereo Amplifier extends the Progression family with a potent stereo amplifier. Leveraging our innovative Super Rail circuitry, first unveiled in the Progression Mono, the Progression Stereo amplifier exploits this unique technology delivering remarkable control and fidelity to any connected loudspeaker.

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 nearly 3,000 VA power supply transformer coupled to 400,000 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. The Progression Stereo is conservatively rated at 300 Watts into 8 Ohms and delivers 600 Watts into 4 Ohms, and properly doubles its output again into 2 Ohms, with a 1,200 Watt power output. The essence of live music, dynamic contrasts, are faithfully reproduced with leading edge transients spectacularly depicted.
