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 m... [more]

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 complementa... [more]

Relentless Monoblock Amplifier
Dan D’Agostino has always had a relentless desire to better his own creations, no matter how flawless they may seem. The Relentless Monoblock amplifier is the latest manifestation of that passion, the result of Dan’s desire for an amplifier that maintains its harmonic integrity and expansive soundstage from 0 watts to 1,500 watts. An amplifier so pow... [more]

Every major section of the Relentless Epic Mono Amplifiers- power supply, input, driver, and output stages - have all been enhanced in this advancement. A new power management topology further isolates the power supply from the entirety of the audio circuitry providing extra protection from the noise the massive power transformers can generate.
The Relentless Epic and Epic 800 employ ... [more]

Perfect Balance and Absolute Fidelity
Crucial to the new circuit are the bipolar transistors powering the front end of the amplifier. Activating the driver stage is a new bias stability circuit providing a nearly 50% increase in operating bias. Increasing Class A operation directly correlates to better sound quality. With this new circuit topology and the unique Copper/Aluminum heatsi... [more]

With its 5.5-kilowatt power supply feeding nearly 100 output devices, the Relentless Mono Amplifier easily delivers 1,500 watts into 8 ohms—and when connected to a 220-volt or greater AC mains outlet, it doubles its output to 3,000 watts into 4 ohms and 6,000 watts into 2 ohms. This power output is maintained with the same musical composure at full power as it is at 1 watt.

Power Supply Highlights
Positioned between the two audio channels, the power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical preamplifier circuits. Internal line conditioning circuitry filters RF noise on the AC power and compensates for asymmetric power waveforms and DC on the mains. Power for the preamplifier stages comes from ... [more]

The Master Power 2+ combines circuitry derived from Dan D'Agostino's acclaimed Momentum amplifiers with advanced features that make it ideal for 2.1-channel music systems and advanced home theaters. The amplifier easily delivers 300 watts per channel into 8 ohms, but this can be increased to an astounding 1,000 watts by bridging the two channels. Switches on the back allow bussing of one signal... [more]
