Now before using the dac and applying the BOM, i wonder if this happenend maybe accidentally by the supplier.
I had the same question a few months ago. All the pre soldered boards come that way and function as they should.

which would you recommend more 4393 or 4396?
2. been meaning to give it a go for some time and have your bom etc. not sure if it's the final one, could you provide links again please - can't find it in search.
3. does the shunt make much difference at all? only, being a novice noob, i'm guessing i'll be content with the sound without the shunt.

many thanks
have BOM now, only really question 1. needs answering if possible, cheers

many thanks indeed, Clave.

do i remember reading that 4396 requires additional 5v, or am i mistaken and just build the board as per your instructions/images (anyone know the answer to this, so i don't have bother Clave?)

cheers

Absolutely not, maybe you're referring to AK4395...

9VA AC for feeding a 5V Salas shunt reg will work, but 12VAC, rectified around 15VDC is better, giving 10V of dropout voltage. I've tried both, and will not go back to the three legs reg for the AK4396 VA. Separate transformers or separate transformer outputs is recommended to isolate analog supply from noisy digital rail.

Hello all,
I have build one DAC with AK4396 and orginal parts over one year ego. Itīs souds good.
So, now I want build one DAC with parts like in the BOM, but without the CS8416.
I have a DSP with a I2S output and this can I connected direct on the input of the AK4396.
I have only one problem: In the BOM isnīt specified the "L1" and "L2".
Can everyone write me what parts can I use?

Thanks,
Norbert

hi clave (or who ever can help), sorry to trouble you. i have shown the bom and all images to my dad and have a query. did search for it, but nothing obvious jumping out.

1. what is the browndog?

2. can you point me to the right posts about how to add that capacitor to the mini board in your images. what exactly was done, unclear from images (for me anyway, trying not to bother dad too much!) - is the board the browndog, is it home made?

cheers guys

BrownDog You can order it with pre-mounted components or do it on your own. Check around the BD site.

Here is a photo. There is more early in the thread I point to when I find it. Note square pad on module.
