Dan D’Agostino Relentless 800 Monoblock Amplifier

Description

The Dan D’Agostino Relentless 800 Monoblock Amplifier is a masterpiece of audio engineering, designed to deliver uncompromising sound quality in a more compact form than its predecessor. It retains the core elements that make the Relentless series exceptional, offering unmatched power delivery and audio performance.

Key Features:

1. Enhanced Circuitry: The Relentless 800 incorporates improvements in every significant section, including the power supply, input, driver, and output stages, resulting in a refined and powerful amplifier.
2. Optimized Power Supply: A meticulously designed transformer featuring multiple sections reduces transformer noise and shields the audio circuitry from magnetic interference. A specialized holder mechanically grounds each capacitor, ensuring stability.
3. Ample Power Output: With a nearly four-kilowatt transformer and a substantial capacitor bank, the Relentless 800 efficiently delivers 800 watts into 8 ohms. When connected to a 220-volt outlet, it doubles its output to 1,600 watts into 4 ohms and 3,200 watts into 2 ohms.
4. Complementary Design: The amplifier features an entirely complementary design with a precision input stage that maintains a perfect balance between positive and negative signal components. This eliminates distortion artifacts and ensures pristine audio reproduction.
5. Advanced Driver Section: The driver section has been upgraded to handle 33% more power per device. The increased transistor count minimizes demands on individual devices, resulting in lower overall amplifier output impedance without the need for global negative feedback.
6. Super Rails Technology: Higher voltage rails are employed in sections before the output stage, effectively enhancing the amplifier’s performance and grip on the speaker. This technology improves dynamics, reduces distortion, and enhances electrical control.
7. Precision Craftsmanship: The amplifier’s chassis is machined from solid aluminum, providing superior shielding, thermal stability, and vibration damping. High-precision milling ensures a stable fit with no visible fasteners.
8. Comprehensive Protection: The Relentless 800 Amplifier features thermal, short circuit, and DC protection, safeguarding against external system faults.
