Description:

The relentless monoblock employs a totally new and complementary topology based on a precision input stage that maintains an essentially perfect balance between the positive and negative components of the signal. Any distortion artifacts that appear in one half of the signal will also appear in the other half, and thus they cancel each other out. The gain circuits operate in the current domain, ensuring that the performance of the relentless Monoblock does not fluctuate no matter the demands. Global negative feedback is not used, nor is it required, as the amplifier's open-loop linearity eliminates the need for this performance-stealing technique.

The core of the power supply is a transformer that uses multiple sections working in concert, all encapsulated and encapsulated in a metal shield. This design reduces transformer noise to near zero and protects the audio circuitry from the transformer's magnetic field. The transformer powers a custom designed rectifier circuit and a 600,000 microfarads / 100 volt capacitor bank. A special bracket mechanically grounds each capacitor so that it does not vibrate. A slow start circuit activates the power supply in stages, eliminating the concern of household circuit breakers tripping on the capacitive input.

Dan D'Agostino's unique Super Rail concept takes full advantage of the incredible resources of this power supply. The Super Rail employs higher voltage rails in the sections leading up to the output stage, effectively "turbocharging" the amplifier and exploiting the full capacity of the output voltage rails, improving dynamics, reducing distortion and tightening grip. power from the amplifier to the speaker.

The unique heat sink of the relentless Monoblock combines copper and aluminum in a heat engine that absorbs heat from connected devices. The elaborate elliptical design expands the venturi heat sink that was first explored in the Momentum series, and ensures that the relentless Monoblock operates safely and reliably even while delivering full power rating. Thermal, short circuit and DC protection are included in a non-invasive yet comprehensive defense against any external system failure.

The entire chassis of the relentless monoblock is machined from solid aluminum, for superior shielding, thermal stability and vibration damping. High precision milling allows the entire chassis to fit solidly with no visible fasteners.

The relentless Monoblock's new power meter measures over 8 inches in diameter. The range and response of the meter automatically adjusts to the level of the incoming signal, making it easy to read no matter how quiet or noisy the musical passage is.

Following in the tradition started with Dan D'Agostino Audio Systems' Momentum amplifiers, the relentless Monoblock offers a single balanced XLR input. Speaker connections are made using solid binding posts made of gold-plated brass.

Just as no audio designer has been more relentless than Dan D'Agostino in his quest for perfection, we believe it is safe to say that no power amplifier has been designed and built to a higher standard than the relentless Monoblock.
