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 NOS uses the AMANERO technology of Audio-GD, in order to use it correctly here the indications of Audio-GD and the download link of the driver: Amanero Combo 384 USB Interface.
It has 6 inputs: BNC / XLR (AES-EBU) / RCA / Optical Toslink / I2S via HDMI / USB AMANERO, whose 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 in all seams with one of the most powerful systems 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 / AMANERO / ACSS
This HE-7 NOS is designed around 8 converters PCM1704UK which work in parallel of a discrete circuit purely symmetric Class-A ACSS without any PDO 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.
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.
These 8 digital analog converters make use of the recognized and confirmed "R2R conversion". The latter consists of directly using the bits of the digital signals to reconstruct theall by acting on a network consisting solely of resistors having a given value (R) and its double (2R), without going through an over-sampling phase.
