AUDIO-GD MASTER-2H

Power Amplifier / Dual Mono / Symmetry Audio-GD MASTER-2H

An exceptional Double Mono Amplifier ...

Audio-GD presents once again the quintessence of the audio technology with this dual mono amplifier with a particularly neat architecture and a formidable robustness.

The famous brand here offers an amplifier with a new output stage (identical to that of the HE-2) in the most accomplished form with outstanding performance: it delivers 2x 250W under 8 Ohm, and 2x 500W under 4 Ohm.

Every product of the brand is scrupulously tested in all seams with one of the most powerful systems in the world: the Audio Analyzer 2700 Series from Audio Precision.

A clean and efficient connection

The MASTER-2H, composed of 2 separate blocks, has a total of 4 analog inputs: 2x XLR and 2x ACSS. The outputs are of course on 2 HP terminals, where you just have to connect your speakers to enjoy.

The result is simple: great musicality, thanks to an exceptional dynamic and a rich sound extrement in detail.

Audio-GD Master-2H

A fearsome HiFi device

Class A Symmetric / R-Core / ACSS / Double mono

This MASTER-2H is equipped with no less than 4 transformers including 2 R-Core for a total of 6000W, 260,000uF of very high-end Nover capacitors, and 80 very high performance MJL1302 / 3281 transistors for the output stage .

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

Audio-GD MASTER-2H
Class A

Class A

A class A amplifier has the particularity of having all its active components always in conduction. They fully amplify the input signal, thereby limiting harmonic distortion on the output signal. The signal sorboth of the Master-2H is therefore of excellent quality, due to the absence of this famous distortion of crossing of the alternations of the sinusoids.

ACSS Technology

Audio-GD has its own signature technology called ACSS for "Audio-GD Current System Signal". Thanks to the expertise and know-how of the firm, this technology offers a less colored, more detailed sound, and an unparalleled neutrality. Every technical engineer of the firm is, in addition to being very experienced, a HiFi enthusiast and audio like you and us.

Des amplis réellement au plus haut niveau
Autant le dire tout de suite, ces amplis monauraux construits radicalement à l’ancienne (circuits symétriques, composants discrets, quasi-classe A) avec une originalité de transmission du signal musical interne par l’intensité du courant et non son voltage (technologie ACSS similaire aux amplis Krell) sont au niveau des meilleurs amplis que j’ai eu l’occasion d’écouter (chez des particuliers ou des salons Hi-Fi). Ils sont exceptionnels et je pense au niveau de ce qui se fait de mieux au monde, mais à des prix 20 fois supérieurs !
La précision, le raffinement des timbres, la présentation spatiale de la scène musicale sont tout simplement les meilleures que je connaisse. On a l’impression de pouvoir toucher la musique, les musiciens et les chanteurs, et ceci sur tous les genres musicaux. Même un orchestre symphonique passe d’une manière comparable à ce que j’entends en concert.
La dynamique est époustouflante. La profondeur des basses incroyable et l’équilibre global à mourir. La musique est douce et ferme à la fois. Les aigus précis, jamais agressifs. La musique coule…
Ces amplis ont littéralement transformé mes enceintes Triangle Magellan, en les rendant encore plus précises, plus vivantes et naturelles. Je ne pensais pas pouvoir obtenir chez moi pareille expérience musicale. C’est à pleurer et mes enceintes me chantent des remerciements. Ma chaîne sonne aussi bien que les meilleures chaines que j’avais entendues jusqu’ici… et c’est chez moi !!! Je n’en rêvais même pas. Le cœur en est ces amplis, la voix mes Magellan. C’est d’une beauté…
Ce Master-2H fonctionne à merveille avec mon Master-11.
En toute sincérité, si vous pouvez vous offrir ces 2 blocs, n’hésitez pas. Ce sont des chefs-d’œuvre. Merci à Audio-GD. Kingwa est un génie de l’amplification ! et merci à Audiophonics de commercialiser ces appareils en France.
