Audio-GD HE-7 NOS

DAC Symmetrical ACSS / 8x PCM1704UK / I2S HDMI & RJ45

Audio-GD HE-7 NOS

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.

Even 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 NOS offers I2S input with its RJ45 and HDMI, to offer excellent sound performance.

It has a total of 6 inputs: BNC / XLR (AES-EBU) / RCA / Toslink / I2S optics via HDMI / I2S via RJ45, SPDIF interfaces are particularly effective for processing data for better audio quality and 3 outputs Analog: XLR / RCA / ACSS.

Each product has been scrupulously tested under all seams with one of the systemstop performers in the world: the Audio Analyzers 2700 Series from Audio Precision.

Fashion without Oversampling "NOS"

The great novelty of this HE-7 is the Oversampling "NOS" mode. The DSP 1 includes two distinct operating modes. This new DSP makes it possible to get rid of the noise problems related to the NOS mode by keeping its advantages in terms of musical pleasure thanks to a filter of -6dB non destructor.

Mode 1 favors the speed of data transfer, the second allows the processing of DSP FIFO with algorithm. The result is a great musicality thanks to an exceptional dynamic and an extremely detailed rich sound.

HIGH FIDELITY in the way Audio-GD

24 bit / 192kHz / 8x PCM1704UK / I2S / ACSS

This HE-7 NOS 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 is equipped with no less than 4 R-Core transformers for a total of 295W, 95,000uF of very high-end Nover capacitors, and high-resistant Dalee performance.

Audio-GD HE-7


Audio-GD has its own technology signature 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.

Chaque engineer technician 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 .
