The Audio-GD Master-10 MK3 sets the standard in the world of high-end integrated amplifiers, combining impressive power with rare sound reproduction finesse. Designed for the most demanding audiophiles, this amplifier stands out for its balanced Class A architecture, proprietary ACSS (Audio-GD Current Signal System), and robust construction designed to minimize vibration and preserve audio signal integrity. With 2x250W power output into 8Ω and a headphone output capable of delivering up to 50W into 40Ω, the Master-10 MK3 is equally suited to the most demanding speakers and headphone listening, offering remarkable sound dynamics and neutrality.
The Master-10 MK3 is based on a massive, ultra-clean power supply combined with a rigid aluminum chassis. These technical choices reduce distortion and improve clarity of detail, even in the most complex passages. The volume control, based on precision relays, ensures smooth and accurate progression, while the balanced ACSS Class A amplification, based solely on discrete components, ensures faithful and natural reproduction, from the most subtle silence to the most explosive crescendos. In addition, the Master-10 MK3's output stage benefits from “Linear Fidelity” technology, which maintains low distortion and excellent linearity.
Audio-GD has focused on component quality and craftsmanship, paying particular attention to every detail. The heavy, sturdy chassis reflects this pursuit of excellence, while offering optimal mechanical stability. The amplifier also features a dual-mono design, which perfectly isolates the left and right channels for optimal stereo separation.
The Master-10 MK3 stands out for its versatility: it can be used as both a power amplifier and a headphone amplifier, with two gain modes to suit all types of headphones. Its balanced (XLR) and unbalanced (RCA) inputs allow for easy integration into any HiFi system, while its negative feedback-free design preserves the purity of the audio signal.
The Audio-GD Master-10 MK3 is capable of reproducing a wide, detailed, and natural soundstage. Whether listening to symphony orchestras, intimate jazz, or electronic music, this amplifier offers neutrality and transparency that highlight every nuance of the recording.
