Default ES9023 / WM8804 S/PDIF DAC Group Buy

Hello All -

This is in continuation to the original thread started by Jean-Paul checking interest on the ES9023 DAC with S/PDIF input. We have a the PCB completed and tested.

The details of the DAC board can be found in


Please list down your name and the quantity required on this thread. I would like to keep this thread open for 15 days and then start working on the pricing.

Note: This group buy is for the PCB and I can make arrangements to get the ES9023 but not for any other components as these are available from Digikey and Mouser. Also this kit is for experienced builders, no extra help can be given as we have lives too. The DAC will work perfectly and perform optimally when built according the BOM with the right skills. We cannot give individual support on this design, sorry.

Thanks pchw for the spreadsheet.

The board dimensions are 3in x 2.2in. The BOM will be posted soon as we are making some minor changes to the board based on our testing.

Pricing Update:

Now that the price has been published please update the spreadsheet with your final numbers. I will start sending out emails to the members from the spreadsheet on Friday. During that time I will close the Group Buy. As I mentioned earlier I will be able to get only the PCB and ES9023.


Bill of Materials:

Update: 06/20/2012: PCB and DAC received from manufacturing. Will start mailing it to the group buy members soon. Pictures posted.

Any options please? If we include chips and components to group buy we may reduce cost anyway.

Edit: It seems first post was already edited after my early read due to this issue
