The Dan D'Agostino Relentless Z Preamplifier represents an absolute triumph in high-fidelity control and signal purity. Available through Trimira Audio, Brisbane’s premier destination for ultra-high-end audio, the Relentless Z Preamplifier incorporates the breakthrough Z Series architecture featuring an upgraded current-capable FET output stage designed to create perfect electrical coupling with matching Relentless power amplifiers.
Utilizing a magnificent three-chassis structure two isolated mono audio channels flanking a central power supply the Relentless Z eliminates cross-channel interferences, noise contamination, and stray magnetic fields to deliver unprecedented transparency, dynamic contrast, and micro-detail.
Key Features & Architectural Highlights
-
Three-Chassis Modular Architecture: Features separate left-channel, right-channel, and power supply chassis mounted via gold-plated inter-chassis connectors to completely isolate audio circuits from AC noise and mechanical vibrations.
-
Upgraded Current-Capable FET Output Stage: The new Z topology delivers exceptional current output capability and stability, enabling seamless electrical synergy with power amplifiers for faster transient speed and punchier low-frequency authority.
-
Ultra-High Input Impedance Front End: Discrete differential FET input stage accepts over 30 Volts of input signal with an input impedance exceeding 1 MΩ, making the preamplifier completely immune to source-matching issues.
-
Zero Global Negative Feedback: Pure, direct-coupled, and fully balanced topology operates with no negative feedback, preserving natural harmonic richness and infinite soundstage depth.
-
Dual-Zone / Two-Source Control: Features twin volume controls crafted from 14 individual metal components each, capable of driving independent sources and volume settings across two distinct zones simultaneously.
-
Proprietary Bi-Directional Bluetooth Remote: Ergonomic machined aluminum and copper remote with a tactile touchpad interface, providing real-time feedback without line-of-sight limitations.
-
Optional Field-Upgradable Digital Streaming Module (DSM): Adds reference-grade digital inputs (USB, Coaxial, Optical, Ethernet, Wi-Fi) with native PCM up to 32-bit/384kHz and DSD256, integrated via a dedicated iOS app supporting Roon, Tidal, and Qobuz.
