The Audio-GD AS-1T is a symmetrical DAC based on a pair of ESS ES9038Pro Digital / Analog converters. This ensures an extremely low level of distortion, very rarely achieved by this type of product and especially at such a low price.
This is 2019 version of D77. It is equiped with the last Accusilicon 318B oscillators to upgrade the DAC precision even further than with TCXO clocks.
The Audio-GD AS-1T is a symmetrical DAC based on a pair of ESS ES9038Pro Digital / Analog converters. This ensures an extremely low level of distortion, very rarely achieved by this type of product and especially at such a low price. The ES9038Pro chips feature 32-bit HyperStream II technology for high audio performance with a dynamic range (DNR) of up to 140dB and a THD+N of -122dB.
The two DAC ES9038Pro are also supported by an FPGA. This one is in charge of synchronizing the audio signals and thus reducing the jitter. In short, it provides a more precise and transparent sound reproduction, while drastically reducing noise. 3 Accusilicon clocks are also integrated, once again allowing the jitter to be reduced to a minimum thanks to optimal signal synchronization.
On the connector side, the AS-1T offers SPDIF Coaxial, Optics, USB-B, a BNC connector and finally I2S HDMI LVDS as input. At the output are XLR 3 poles, ACSS and RCA Stereo. A complete panel of connectors that satisfy the vast majority of needs, for easy integration into your audio system.
Who is the Audio-GD AS-1T for?
Unlike the other products offered by Audio-GD, this AS-1T does not have discrete outputs. It incorporates AOPs and has been optimized to offer the best possible technical specifications. It is therefore addressed to a different audience, mainly interested in exceptional measures and wishing for unfailing transparency. This exceptional sound fidelity also allows cables, rooms, speakers or any other audio product to be tested under optimal conditions.
Supported sampling rate
USB / I2S : PCM up to 384kHz - DSD up to DSD512 Coaxial : PCM up to 192kHz Optique : PCM up to 96kHz
