Good initiative rvrazvan ! However I feel it is better to start a new separate thread on this for instance with the title: "Case for group buy ES9023 DAC" or something like that. Just to keep things concentrated.

What material will be used ?

Well...i would like something like this
Click the image to open in full size.
Or this(not a dac, but i like it)
Click the image to open in full size.

I will use some wood/venner for aestethics. Aluminium or 2mm steel for the rest, powder coated. It will be alot cheaper if i stick to 2mm sheet metal.

I want the price to stay below 50$.

I was thinking of making small case from solid bullet aluminum just to fit the board but cost is too high.

I have one of the units completed for sale. It was built by JP himself. It sounds exceptional and is the equal or better of anything I have in house, cost no option. Please pm me if you would like details/photos of it.

Thank You!

I kind of like the "new meets old" feeling of the WM8804-ES9023-LM723 combination. No rational explanation except for the very low noise of LM723 (2.5 uV !!!).

LM1084 is more noisy than 7805.....it is a 5A reg which seems overkill too.
How to calculate Rsc?
And What is minimal input voltage with 5v out?

Hi Åke, we are still looking for other (discrete) solutions as LM723 needs at least 9.5 V input voltage. We are also willing to know how many of the group buy participants would like to have a power supply PCB too. For calculating Rsc please see data sheet of LM723.
