Some days ago I received some ad, from I don't remember who, offering their new "extraordinary" DAC based on the recently released ES9038. Their words, not mine. So first I went to eBay and searched the DAC chip, and found this DIY board: http://www.ebay.com/itm/ES9038PRO-U...:m:mcLdLP2_Pgt1lQ8Vm5X80Aw&afsrc=1&rmvSB=true After that I could find out there's a similar board with the ES9028, and that the ES9038 is simply eight ES9028 in one single chip. As there are no schematics on the ad, who knows what they did with the other six channels (???). Maybe someone here has used this board or the former ES9028 based one, and can chirp in the good and the bad things of this project.
