Dan D’Agostino Master Audio Systems, industry leader in high-performance audio electronics, is pleased to announce the introduction of the new Relentless Z Preamplifier, along with the Relentless 800Z and Relentless Epic 1600Z Monoblock Amplifiers.

THE RELENTLESS Z SERIES

The breakthrough development of Momentum Z technology directly inspires the new Relentless Z upgrades, elevating our flagship products to an entirely new echelon of performance. Alongside profound sonic refinements, this architecture delivers massive power gains. The Relentless 800Z now outputs an astonishing 1,200 watts into 8 Ohms, while the Relentless Epic 1600Z commands the room with an extraordinary 2,200 watts into 8 Ohms. Eclipsing the original Relentless components, the new Relentless Z Preamplifier, combined with either the Epic 1600Z or 800Z Monoblock Amplifiers, optimizes the electrical interface between preamplifier and power amplifier—unlocking unprecedented system synergy, control, and musical realism.

“The Momentum Z series was such a profound upgrade, we just had to explore adding the Z topology to our flagship Relentless components. The results are astonishing.”

At the core of the Relentless Z Preamplifier development is a reimagined output stage. The introduction of a current-capable field-effect transistor (FET) architecture enables significantly greater current delivery and enhanced stability. This pairing creates a highly optimized interface—a preamplifier capable of delivering current with precision, and an amplifier designed to receive and utilize it effectively.

This advancement allows the preamplifier to drive the optimized input stage of the Relentless Epic 1600Z and the Relentless 800Z Monoblock Amplifiers with greater authority, ensuring that the full capabilities of the Z circuitry are realized across the system.

FETs are widely recognized for their suitability in high-performance audio applications. Their inherently high input impedance minimizes loading on source components, preserving signal integrity, tonal balance, and dynamic nuance. Additionally, their low noise characteristics and excellent linearity make them ideal for handling delicate signal levels at the front end of amplification stages. Unlike bipolar devices, FETs operate as voltage-controlled components, requiring minimal input current and delivering smooth, highly linear transfer characteristics contributing to lower distortion and a more stable interface between components.

In the Relentless Epic 1600Z and Relentless 800Z Monoblock Amplifiers, the Z circuitry takes a novel approach by intentionally lowering the traditionally high input impedance associated with FET designs. This allows the amplifiers to draw more current from the Relentless Z Preamplifier, strengthening the electrical coupling between components. The result is improved transient response, enhanced dynamic contrast, and a more precise rendering of musical detail.

One of the most notable sonic benefits of this architecture is a significant improvement in low-frequency performance. Bass reproduction gains greater texture, control, and authority. The increased output power of the Relentless Epic 1600Z and Relentless 800Z Monoblock Amplifiers further cements their positions as unflappable power sources for any musical demand, from any loudspeaker.
