A resolutely high-end DAC

Audio-GD offers with its D77 balanced DAC a top-of-the-range HiFi product, intended to provide the most audiophiles with a very high quality reproduction. For that the brand does not skimp on the means by integrating high-end components: Double converter ES9038Pro, FPGA Altera Cyclone, USB Amanero interface and two Accusilicon 318B clocks .

USB Amanero interface and HDMI I2S

As usual, Audio-GD chooses to integrate an Amanero Combo 384 USB interface in its device. This supports high sampling rates and bitrates, up to 32bit 384kHz, as well as DSD. The DAC also has an HDMI I2S input, allowing you to take advantage of these sample rates and bitrates as well. Enough to appreciate his music in the best of ways.

Attention: To use the USB interface from a Windows device, please install the following driver : Download Amanero USB driver.

Discrete output stage

The last stage of the DAC is its analog output stage. This is extremely important to ensure excellent sound quality. For this it uses a design based on discrete transistors and Vishay resistors. Output buffers are balanced FETs. In addition, the ACSS outputs operate in pure Class A and without feedback, so as to offer the purest and most faithful sound possible.

A consistent PSU

The Audio-GD DAC has a total of 14 power supply units. 11 ultra-fast linear power supply units combined as a two-stage power supply allow the digital circuit to obtain a clean power supply signal.

In the same way, 2 groups of pure Class A power supplies can supply the analog circuit.

Finally, a separate power supply circuit powers the display and control system to avoid electrical disturbances.
