Audio-GD MASTER 10 MK2: High performance amplifier

Audio-GD once again brings us the quintessence of technology in audio with this Master 10 MK2 amplifier with a more than neat and clean architecture.

The renowned high-fidelity audio brand offers us here an amplifier in its most advanced form with outstanding performance: it delivers 2x 250W into 8 ohms or 2x 500W into 4 ohms.

Each brand product is rigorously tested using one of the most powerful systems in the world: Audio Precision's 2700 Series audio analyzers.

Master 10 MK2 has 5 analog inputs: 2x RCA / 2x XLR / 1x ACSS. The output is of course on 2 speaker terminals where you just need to connect your speakers to enjoy.

The result is unmistakable: superb musicality thanks to exceptional dynamics and a rich sound that is extremely detailed in every way. We can tell you that you are getting close to – if not achieving – perfection with this HiFi device.

The Master 10 MK2 uses a durable aluminum alloy chassis to prevent transformer eddy currents from affecting audio circuits. Thus, the internal structure of the Master 10 MK2 is divided into two sections by aluminum plates. The AC power cable is also shielded.

Vibrations are also taken into account to promote the best sound reproduction. Each amplification channel is located under a 5mm thick aluminum plate, which not only effectively dissipates heat, but also avoids vibration.

This Master 10 MK2 is equipped with no less than 4 transformers including 2 R-Cores for a total power of 1500 W, 140.000uF of very high class capacitors and 24 very high performance ON Semiconductor transistors for the output stage.

This amplifier is also designed based on a purely symmetrical discrete ACSS circuit, with a separate power supply to avoid any interference or electromagnetic disturbance of the signal.

The volume control is also optimized, with 4 channels and 99 steps, digitally controlled by relays to avoid channel balance problems and improve sound quality.

A special feature of the amplifier is that all its active components are always in a state of conduction. They fully amplify the input signal, thereby limiting harmonic distortion in the output signal. Therefore, the Master 10 MK2's output signal is of superior quality due to the absence of the famous sine wave transition distortion. Its gain and preamp stages operate in Class A, using discrete components, with no PDO or coupling capacitor in the signal path.

Each technical engineer of the brand, in addition to experience, is a HiFi and audio enthusiast just like you and me. To know when the ACSS output is being used, the XLR and RCA outputs are switched to MUTE mode.
