The Relentless Epic 1600 to Epic 1600 Z Upgrade transforms original Dan D'Agostino Relentless Epic 1600 Monaural Amplifiers to full flagship Epic 1600 Z performance standards. Facilitated through Trimira Audio, Brisbane’s premier destination for ultra-high-end audio, this factory-authorized enhancement elevates power output, dynamic headroom, and system synergy without necessitating component replacement.
Featuring breakthrough engineering derived directly from the Momentum Z and Relentless Z development programs, the upgrade boosts power output to an extraordinary 2,200 Watts into 8 Ohms and introduces an advanced Z JFET-based input stage to dramatically increase current transfer and electrical coupling.
Key Features & Technological Innovations
-
Power Output Elevated to 2,200W @ 8Ω: Pushes absolute power delivery to 2,200 Watts into 8 Ohms (scaling linearly to 4,400W into 4 Ohms and 8,800W into 2 Ohms), offering unmatched micro-dynamic expression and structural bass control.
-
Z JFET-Based Input Stage: Incorporates a redesigned, ultra-low-noise JFET input architecture. This allows the amplifier to draw substantially higher current from preamplifiers—particularly the Relentless Z Preamplifier—strengthening signal transfer and lower-level detail resolution.
-
Enhanced Electrical Coupling: Maximizes signal purity and impedance matching between front-end preamplification and the main power stage, resulting in effortless transient speed and a vast three-dimensional soundstage.
-
White-Glove In-Field Service: Executed on-site in the owner's home or listening room by certified Dan D'Agostino Master Audio Systems (DDMAS) factory technicians, eliminating shipping risks and logistical delays. (Note: DDMAS technician travel expenses are billed separately).
-
Complete Circuit Alignment & Testing: Includes comprehensive bias adjustment, thermal verification, and bench-calibration on-site to ensure optimal operating specs and long-term reliability.
