After setting the measure for amplifier excellence, the Relentless Monoblock Amplifier underwent a substantial upgrade combining new circuit sections and components to become the Epic 1600. Just as no audio designer has been more relentless than Dan D’Agostino in the pursuit of perfection, no power amplifier has been designed and built to a higher standard than the flagship of the Relentless family.
A true balanced design—unlike conventional bridged amplifiers—it uses a single front-end topology, based on current mirror circuitry to derive the symmetrical plus and minus rails. Typical bridged amplifier designs use two front end circuits, making it virtually impossible to achieve perfect symmetry between the plus and minus rail. In the Epic 1600, distortion artifacts that appear on one half of the signal will also appear on the other half and thus cancel each other. This unique circuit configuration allows for awesome power output with strikingly low distortion. New input stage devices deliver a 300% increase in current as compared to the previous devices, extending low- and high-frequency performance, while truly impressive distortion figures result from the use of no global negative feedback. The amplifier’s open-loop linearity eliminates the need for this performance-robbing technique. Gain circuits operate in the current domain, assuring that performance does not fluctuate regardless of the current demand.
With its 5.5-kilowatt power supply feeding over 100 output devices, the Relentless Epic 1600 Monoblock Amplifier easily delivers 1,600 watts into 8 ohms—and when connected to a 220-volt or greater AC mains outlet ,it doubles its output to 3,200 watts into 4 ohms and 6,400 watts into 2 ohms. This power output is maintained with the same musical composure at full power as it is at 1 watt.
