DAM1021 R2R DAC build (awesome)

For sale is a project that didn't quite make it to the finish line, for a number of reasons...

This is a DAC project based on the Soekris DAM1021 R2R ladder DAC (0.02%), and was eventually meant to be housed in a beautiful custom made case, together with its power supply and USB converter. Maybe have a look at the images first, you literally get the picture.

The project includes the DAC board, the complete power supply (with two Jan Didden super regulators for the board and two TPS7A4700 regulators for the converter and isolator), two transformers with a rectifier and prefilter board, a DIYINHK USB converter and matching isolator, and the custom made case (precision cut from a block of ureol). The components are all mounted on an anodized aluminum plate that is to be mounted bottom up into the case.

The power supply is fully working and can be configured for 115V and 230V mains voltage. It just needs a bit of fiddling around the isolator to play music, all boards are fully functional! I am doing my listening from a modified SD card player hence the sale.

I will ship to everywhere in the world.

Asking price is 280$ (a steal, the case alone is....dada dada 😉), open for reasonable offers.
