Not sure where I should be posting but are there any guides on a DIY DAC?
I don't mean some discrete R2R DAC or anything like that I mean using ICs. My knowledge of coding is near zero same with fair bit of the digital design side. Got no problem with analogue though, anyone know of anything?

Ultimately want low THD (<-115db THD) and noise, again analogue electronics side is no problem.

Was thinking of a ESS9038pro?
But as I have had no experience anything I could start with to learn?

I do not like the ideea to have n the same package complex digital schematic together with low noise analogic circuit. I simply do not have trust that The digital noise will not go in the analogic low noise circuit. The measurements can be easy made to show low noise and distorsionează by simplu don't measure n the right spectrum zone.

Lovely work.

Very nice,

can we have some more pics of the external casework?
Also, where did you get the case? Did it come with those internal separation pieces? If not, where did you source those?

I always find doing the casework the hardest part !!

Cheers,

P.

Hi Percival007,
The case from China (~25$)
And I did internal separation of the plastic (10mm) and the copper tape.
It's good for unti-noise.
Cheer,
