@danager @fuzztone Thanks for the recommendation. I have both of them. I am sure that I can buld something around Raspberry PI .. that might be good DIY as well.
For miniDSP, this way above my target budget .. It is definitely a very nice evice but again it is pricey even compared with Matrix audio mini pro, which I was considering...
I was checking bluesound node (range) for a while and even If I thought that they are great in many ways (design, OS, decent sound and convenience mostly) I had an impression that they are not giving any digital inputs... I checked the most recent one again I saw that they are providing optical input and most importantly HDMI eArc input to make it perfect combination with my new TV.
What I see is convenience and practically on these are second to none in the price range. I will probably go to that direction,
Thanks for your recommendations.
