Current highest bit rate is 192KHz, we have not try out the 384kHz and not sure whether works.
The DSD data pump to I2S bus is software implementation and needs developers to try out. However, the ES9023 DAC don't accept DSD data and needs to convert over to PCM.
Design a small adapter for Euler I2S pins over u.fl is possible. However, this depend on collaboration and popularity.

Thank you for the answers, few more questions if I may.

Just for clarification - you referenced 192KHz and 384KHz because they are the highest frequencies above 176.4KHz, 352.8KHz or because you only support 48Khz family as beaglebone does?
https://hifiduino.wordpress.com/2014/03/10/beaglebone-black-for-audio/

So DSD over I2S is only a software issue, no hardware limitation on DSD out with:
64 Fs: 2.8224 MHz, 3.072MHz,
28 Fs 5.6448MHz, 6.144MHz,
256 Fs: 11.2896MHz, 12.288MHz

ES9023 DAC don't accept DSD data, but ESS9018 does

What I2S input formats do you support?

Agree low costs and god performance DAC i2s board , is pine64 project.
and  ES9023 DAC sound is not too bad !

if you design ES9023  DAC i2s for pine64  you will support Volumio ?
This is Media player , boot from image file
if you can , try give Development board to Volumio or contact they

Volumio works on embedded systems , is open source .
someone is designed for Raspberry Pi  ES9023  DAC  support Volumio
https://volumio.org/

We are happy to provide Pine A64 board and DAC module to Volumio when ready, this will happen some time around March. Do you have the Volumio contact info?

No , this web site i just to saw ,  ask you 
I am not S........

Noted.

>Yes, if you plan to natively decode DSD, ESS9018 is a best choice. Please note that DSD and DSD2 make sense, Above 2XDSD is just
>plain silly and number games.

yes I know this numer games, I was asking to get the whole picture right.

>In general, the I2S input formats is Philips type. However, the hardware also can handles EIAJ type (also call as Sony type),
Do you also support up to 24 bit 192Khz on the I2S input?
I could not find Master Clock input for the I2S input - is there one?

It would be great for other users to have this information on the pine64 audio wiki page

This is low costs and god performance

This is low costs and god performance
PINE boards Euler "e" Connector  support DAC 3.3V + 5V Spdif
