Thanks.
Suddenly got a new problem too - yesterday it was completely smooth sounding (Lusya Power Filter purification board into a Lusya DAC into a Raspberry Pi 3b). No hissing, really clean sounding.
Today by accident, another (powered) micro USB cable touched the board - now I get hissing from it non stop.
I've tried:
1. Changing from RCA output to the 3.5mm output
2. Changing to the 3.5mm output of the Pi itself
3. Powering through the Power Filter Purification Board
4. Powering through the Pi directly
5. Removing the Power filter purification board (no change to hissing) - when plugged into RCA or 3.5mm
6. Removing the DAC and plugging directly into Pi 3.5mm - hissing reduces but still a static/wind like noise.
All options are giving me a non stop hissing sound coming.
Any suggestions?
Hoping I didn't cause perm damage - want to go back to the high quality, clean & clear sound I had yesterday.
