Update:

- Listening via Roon as I type.
Big thanks to Jesus & Andrew for awesome support.
Thanks to AC members who chimed in offering their assistance.
The sound is really good via Roon, no comparison to any other devices I have yet. Giving it some break in time.
I did however try HQ Player Mode, big popping sound at the beginning of a track. That will be for another time.
Hope I can figure things out. I do like how HQP sounds via my Mac Mini. Have to see what's what.
* Get the same popping in Roon as well, it is at the beginning of an album or if I pause/play a track.
Very happy it is finally working.
