Previewed ES9026PRO chip that came earlier for the prototype and testing. Final product will look different with ES9038PRO chip.
I like to know the output voltage exactly before preordering the board. My I/V stage has not unlimited amplification capability.
Is the users manual available to download?
This is an current output dac chip, exactly like the ESS9018. So either you put it directly into an i/v converter with adjustable output level - or you use resistors to passively choose output level before your gain stage.
I haven't read what current it outputs - but with the 9018 it is 8mA/phase in stereo mode. So it will suit anything following after, but it perfers low input impedance to perform it's best (which is many, many times lower THD than your average tube stages).
8 CH version will be AKD38 possibly after this 2CH one if there is sufficient interest.
Power supplies are external with this current design so you could use anything suitable that you fancy but at this stage there are no plans to use the ES9311 as such.
That's really good news! Not long to go before I can listen to a DAC chip with the best technical performance in the world? Wow!

The current mode THD+N is -122dB. Can't find voltage mode in the 9038 datasheet. If there is the same difference between I and V modes as the 9018, voltage mode output would be -110dB...
Such delay in production up to the holidays could only mean they can't defeat some issues in the dac. I guess we can expect it won't be perfect as well as 9018.
The chips have finally arrived. These are production versions so I guess known bugs have been fixed
Somewhat different from the sample version that I was using for tests so changes to board layout and controller firmware required. I must admit there is a fair amount of complexity compared with the 9018 but mostly sorted with the final board design and will release for fab sometime next week.
For those who have ordered, updated support information has been emailed already. In case you have not received it please let me know.
I am working hard to get this project materialized. There are lot of things to consider to build up a DAC system and the chip is just one of the components.
Thank you for your patience!

All indications from my tests so far shows that it is better than the 9018 DAC.
So what are you waiting for😀
I didn't wrote the one is better the other worse. It's obvious in datasheet.
As we know, 9018 is not perfect and has some drawbacks. Newer one won't be an exception I guess, but we shall see.
Could you specify in details, which things to consider to build up a DAC system? We can discuss it here and choose better solution.

Congratulations Acko. It looks like you will be the first into production with this DAC chip with the best technical specs in the world. Really looking forward to it.

Hi,
There are numerous requests for empty boards from diyers who would like to build up on their own, have a bit of fun and also learn how to build a DAC system - but I must warn you that there is a fair amount of complexity soldering tiny parts. There are risks involved and you may end up with thrash. Given that chip alone is $75 this can be painful!
Anyway for those who still prefer this challenge (or as souvenir 😀) , empty boards can be supplied at $30 US each. No components mounted or supplied. Minimum order 300 pcs, so Group Buy arrangement. If interested please put your name down on the list below. Schema, BOM and support information provided with this
1. Acko - AKD32 DAC bare board x1
