It’s a Pi3 + HiFi Berry Digi Pro. I’m using the coax output of the Pi to drive a Cambridge Audio Azure 851D DAC, which drives an Emotiva 2 channel power amp.
The 198k file is a FLAC on a USB thumb drive that is plugged directly into the PI.
I’ve been playing other ripped CDs since then with no issues. All of my media on the thumb drive is FLAC.
