I was up to building my own streamer. I have good hifiequipment at home and wanted just the best digital output I could get feeding my DAC.
I started with some reading and a Digi + Pro with separaded and good powersupply would do the job.So I separated 5V and 3,3V to digi board and put it into a nice case.A good transformer is needed and also regulated sirquits. I Also wanted better wifi than included in raspberry so i desoldered the orginal antenna and soldered external antenna.
My case did not permit USB in the direction for Raspberry so i desoldered one USB port and found one for external schassie mount standard.
Im wery happy with the result and its sound fantastic :)
