I have built a new streamer. After reading endless discussions on diyaudio i did this:
Raspberry Pi3 with Hifiberry Dac+ Pro with three power supplies:
1. iFi ps for Pi, connected directly to GPIO pins 6 (gnd) and 2 (+)
2. 3.3V ps with LT3042 for clocks and the digital part of DAC + pro connected to pins 20 (gnd) and 1 and 17 for (+). You have to bent PI3 pins 1 and 17 on gpio header, than DAC will not get 3.3V from Pi

3. 3.3V ps with TPSA4700 for the analogue part of DAC + pro. You have to remove R14, than DAC will not get 5V from Pi and then connect the + on the output leg of 3.3V reg

One 50VA 2x6V transformer for ps 2 and 3.
I have changed caps C7/C8 after PCM1522 for Digikey P/N PCF1457CT-ND Panasonic ECH-U1C222GX5. SMD parts are nightmare.
SQ is phantastic. I also tried Volumio instead of my beloved picoreplayer and IMHO it sounds much less digital and just overall better, than pcp ...
No more server, i connected hd directly to Pi.
I will post some pics and details later.
