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.
The Relentless Monoblock employs an all-new, fully complementary topology based around a precision input stage that maintains an essentially perfect balance between the positive and negative components of the signal. Any distortion artifacts that appear on one half of the signal will also appear on the other half, and thus cancel each other. The core of the power supply is a transformer that uses multiple sections running in concert, all potted and encased in a metal shield. This design reduces transformer noise to near zero and protects the audio circuitry from the transformer’s magnetic field.
Dan D’Agostino’s exclusive Super Rail concept makes maximum use of the incredible resources of the amplifier’s power supply. Super Rail employs higher voltage rails in the sections prior to the output stage, effectively “turbocharging” the amplifier and exploiting the full capability of the output voltage rails—which improves dynamics, lowers distortion, and tightens the amplifier’s electrical grip on the speaker.
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 together solidly with no visible fasteners. A new power meter, designed specially for Relentless, measures more than 8 inches in diameter. The meter’s range and response automatically adjust to the level of the incoming signal, making it easy to read no matter how quiet or loud the musical passage.
