ES9018K2M chip has been revised, new version comes with more functions than the old one. Everyone participating will get the new chip. Will post the DAC photos next week or earlier.

There is no link available, you can ask your country ess distributor regarding this. There are few new functions the gpio pins can be configured to have spdif input, now we can have up to 5 spdif inputs, over sampling filter bypass, custom programmable FIR filter coefficients, minimum phase filter, also one regulator can be omitted from the existing schematic.

Ess is not sharing datasheets to everyone only if you buy from them and sign an NDA.
You're absolutely right atupi, I know about ESS NDA restrictions 😉
Syllabe may have some hints or links to share...
3 SPDIF are more flexible even if one of them remains unpopulated/unwired.

New update... there will be additional I2S isolation feature on the DAC board. On the test board I did not put that but on the new board members will be receiving it will be there. Buyers can populate or not populate the I2S isolator section at their own discretion.

Could you consider adding pads for SOIC opamps in the I/V? The choice is much larger in SOIC and many of the newer and better opamps are not offered in DIP. As it is basically a SMD proyect, IMO it would make sense.
You can use SOIC to DIP adapter board. The main reason I have used DIP option is that you can swap different opamps even if it is smd type with adapter boards which are easily available on eBay

Using adapters adds extra length to the path to decoupling caps which can cause trouble with some opamps. I've had osillation issues when using adapters.
Okay here is the photo link for the dac. It was taken using my mobile and it did not come well. I will post good photos little later.
