One of the best DACs in the world ...

Audio-GD introduces us once again to the quintessence of audio technology with the products of the series HE, evolution of the series MASTER. They have enjoyed the longest duration of design and testing in the history of the famous brand.

Samee if Audio-GD had already studied the products since 2006, the best technicians of the firm offer them here in the most accomplished form with extraordinary performances and unthought.

Exquisite interior and connectivity

This Audio-GD HE-7 uses the AMANERO technology of Audio-GD, in order to use it correctly here the indications of Audio-GD and the link of download of the driver: Amanero Combo 384 USB Interface.

It has 6 inputs: BNC / XLR (AES-EBU) / RCA / Toslink / I2S Optics via RJ45 / USB AMANERO, with SPDIF interfaces that are particularly effective for data processing for better audio quality and 3 analog outputsXLR / RCA / ACSS.

Each product has been scrupulously tested in all seams with one of the most powerful systems in the world: the Audio Analyzers 2700 Series from Audio Precision.

HIGH FIDELITY in the way Audio-GD

24 bit / 192kHz / 8x PCM1704UK / AMANERO / ACSS

This HE-7 is designed around 8 PCM1704UK converters that work in parallel with a purely symmetrical Class-A ACSS discrete circuit without any AOP with separate power supply.

It features no less than 4 R-Core transformers for a total of 295W, 95,000uF of high-end Nover capacitors, and high-performance Dale resistors.

ACSS

Audio-GD has its own technology signature called ACSS for "Audio-GD Current System Signal". Thanks to the expertise and know-how of thefirm, this technology offers a less colored sound, more detailed, and a neutrality without equivalent.

Every professional engineer of the brand is, in addition to being experienced, a passionate of HiFi and Audio like you and us. That is, when the ACSS output is used, the XLR and RCA outputs go to MUTE.

8x PCM1704UK

These 8 digital analog converters make use of the recognized and confirmed "R2R conversion". The latter consists in using directly the bits of the digital signals to reconstruct the analog signals, all this by acting on a network constituted solely of resistors having a given value (R) and its double (2R), without going through an over sampling phase .
