Assembled ES9023 dac sold out. I can take pre-orders for the assembled dac if someone interested or i can sell the bare board with es9023 soldered and one hcmos crystal unsoldered. Buyers can use this crystal or can use ultra phase noise crystal. Buyers will get full bom and component layout plan. No schematic will be given out. The dac can be easily completed using the provided component layout plan. This is fully tested design and gives out rocking performance for the price and size. The dac board size is about 11 cm (l) x 6 cm (b) x 2.4 cm (h) . The es9023 dac board+es9023 chip+ hcmos crystal is $38+$10 shipping.

Kindly read "ultra phase noise crystal" in the above passage as "ultra low phase noise crystal". Its a typing error. All components are easily available from digikey, mouser and ebay. The standard free crystal will be given as soldered on the board or unsoldered depending upon the buyers wish. The dac board has auto source selection and spdif signal locking, usb and power on status will be indicated by the LEDs.
