Folks: please be aware that this SPDIF version GB only lasts one month. Don't start emailing after that if we still have boards. We won't. This PCB is produced only for the large demand after the previous GB ended and also for people that heard about this DAC when the GB was over. So if you think this is a nice SPDIF project order a PCB now.

hi there,
first: congratulation for reaching the end of this challenge, i'm following it since it's beginning, i'm very happy that you succeed in it!
as said by someone else before, i'm crossing fingers for having also a BOM GB in order to have everything for soldering ;-)
thank you again
(New GB form filled)

Default Congrats!! Any change of pre-soldering the DAC chip?

Hi JP - Subbu


Is there any chance you offer the PCB with the chips soldered?

This would make the hit rate a lot higher for me ;-) For now I have put 4 sets in the spreadsheet hoping to have 2 working DAC's (at least that is).

Same question here? I didn't see the answer?

Just to know, to order one or two PCB?Chip-s?

Regards and congratulations on finishing this project,

dear @unixdeveloper,
please update this thread with the according prices for the 2 PCB's and the 2 main components, the ES9023 and also for the WM8804 receiver (in case that you are possibly offering this one too in this GB); shipping prices would also be important so that we can estimate total costs and make up our minds on how much we can order from our dedicated budgets for this long waited GB,

Added myself to the spreadsheet and filled in the web form thanks.

I would also like the chips to be soldered if possible please. No problem if there is a surcharge for this.

Hi All

I've upgraded the original thread with new informations.
Concerning the parts GB, it's still on the way.
About ES9023 DAC chip soldering, Subbu is the only one who could tell us...
With a basic soldering skill and the informations delivered in the "Build Guide" everyone will be abble to achieve this task safely for the chip !

I need some missing informations before publishing BOM's new prices.
As you know the Subbu DAC V3 is now splitted in 2 versions : SPDIF and I2S (to come).
Now, you're registering for the SE SPDIF version.
More to come

You're right ByronInLawrence, I'm wondering about doing it.
Consider you won't be abble to discover that the chip is fried until the complete built.
You can't check the DAC to be "safe" before, even if the ES9023 soldering seems fine.
The only way I see it is to offer a fully assembled & tested DAC.
Acting like this will exclude all risks, BTW transfered to the builder

Don't send me PM for details about this option.
I've to think about how much to charge for this service (labour hours + faulty parts risks).
More to come



PS : ByronInLawrence's Post has just collapsed right now while I was writting this answer

This is written on the first post of this thread:

BOM and Build Guide will be sent to the members during the payment period, which should give them enough time to source the parts.
