Every audio designer has a product they’ve always wanted to make but never could.
Either they worry it would be too costly for their customers to accept, or they fear it
would be too far ahead of its time, or they lack the resources to fund the research and
development process. But thanks to the incredible support and encouragement that our
customers and dealers have given me since our founding days, I finally felt I could build
the amplifier I always dreamed of making: the Relentless monoblock.
The Relentless monoblock is the product of a simple question: “What amplifier would
I build if I could build any amplifier I wanted?” The simple answer is: an amplifier without
any limits.
Of course, every amplifier has at least one limit: the amount of power it can pull from
a household AC circuit. But the Relentless is designed to work not only with standard
110-volt AC, but also with 220-volt/30-amp circuits, which allows it to deliver a staggering
6,000 watts of continuous power into 2 ohms. With the Relentless, every speaker ever
made can achieve its best possible performance.
I designed every stage of the Relentless from scratch. The unique input stage achieves
extraordinarily low noise and distortion by assuring that the positive and negative halves
of the signal are perfect opposites of each other, even if the incoming signal is not
perfectly balanced. The gain stage operates in the current domain instead of the voltage
domain, so it cannot be affected by fluctuations in the speaker’s impedance. My Super
Rail design provides additional voltage to the gain stage, effectively “turbocharging” the
output stage to deliver even greater dynamics and maintain an even firmer grip on the
speaker. The linear open-loop response of these stages allowed me to eliminate global
feedback, and thus preserve the music’s subtlest details.
I couldn’t have built the Relentless if I weren’t confident that my customers and dealers
would back me in my efforts to create the world’s best audio components, bar none.
I thank you for purchasing this amplifier… and for believing in my vision.
Sincerely,
Founder, CEO, and chief designer of Dan D’Agostino Master Audio Systems
