ES9038Q2M DAC Module

DAC Module I2S Optical Coaxial 32bit 384khz DSD256

Module DAC ES9038Q2M I2S Optique Coaxial 32bit 384khz DSD256

This DIY module based on a DAC I2S ESS ES9038Q2M offers many possibilities of use in a compact card format. It has I2S, SPDIF Coaxial and Optical inputs and a RCA Stereo output as well as a 3.5mm jack. On the component side, this DAC module includes a 100MHz master clock making it compatible with many DSP cards on the market. Among the options available, it is possible to change the original AOP 5532D mounted on a DIP8 bracket to adapt the sound reproduction of the DAC to its listening.

Modular power supply section

A good DAC must be powered by a quality power supply. The module is delivered configured to work with a simple AC adapter or a conventional 15V DC linear power supply, to be connected to a 5.5/2...5mm jack connector. It is also possible to power this DAC via the +15/0/-15V DC balanced input. To do this, it is necessary to solder between the central contact and the left contact of J6, and to unsolder the right contact.

Configurable digital filters & integrated controls

Thanks to its 100MHz digital master clock, it is sufficient to input an I2S DATA, LRCK and BCLK signal from a USB to I2S interface, for example, to obtain a DAC of a formidable quality. This DAC also has Coaxial and Optical SPDIF inputs that can be configured via the module's DIP Switch..

In addition, the module includes 3 control buttons. The VOL + and VOL - buttons are used to adjust the volume. It is also possible to add an external potentiometer on this module (sold separately). A short press of the MODE button switches to Mute mode and a long press of the same button selects the active input. LEDs on the card indicate the active input.

Fantastic DAC!
Tried this ES9038Q2M for testing. For the relatively small price paid for this board, you get a very good DAC. Tested with a single rail 15V supply and connected Raspberry Pi 3B+ (over I2S) with separate 5V SM supply. Using piCorePlayer 4.1 (I-Sabre-ES9023 DAC, native/DoP DSD Squeezelite binary, card control: 384k) the sound is amazingly clear and distinct and the bass is well-balanced. You can pin-point the instruments in a symphony orchestra. Was able to play DSD128 files (DoP) without any problems.

The board comes with a 5532D opamp. Looking forward to testing the board with a Muses opamp and a dual rail 15V linear PSU.
