The Relentless Epic 1600 is the most powerful amplifier Dan D'Agostino has ever built. It delivers 1,600 watts into 8 ohms, doubling perfectly into 4 and 2 ohms — 6,400 watts of current capability that can drive any loudspeaker ever made to its absolute limits.

But raw power is only half the story. What makes the Relentless extraordinary is its ability to play at whisper-quiet levels with the same refinement and detail resolution as at full output. The Super Rail Topology power supply maintains voltage stability across the entire dynamic range.

The chassis is machined from solid aluminum with copper Venturi heatsinks — copper's thermal conductivity is 91% greater than aluminum, enabling the Relentless to sustain high power output indefinitely. The Ballistic Meter with mineral glass face provides real-time power monitoring.

Each Relentless is hand-built at D'Agostino's Cave Creek, Arizona facility by a small team of dedicated craftspeople. It is, by any measure, one of the most extraordinary amplifiers ever conceived.
