It is indeed not easy. Maybe I didnt explain myself that good in the previous post.
The reason for my search is that I practice/play the drums and I do this by playing along with music via Tidal/Roon.
So the best way would be via wireless headphones, since that gives me the most maneuverability and with the best possible quality of music in my ears and on top of that with a reasonable budget ( I know, a huge mountain to climb
).
But indeed, maybe via a cable is still the best way to channel music to a source, for now.
Anyway, I thank both you and Gregadd for your help and suggestions.
Both of you have shed a lot of light in the darkness
Thanks!
