Hi, I am posting this along another reply for Intel NUC 11gen.
When I used 2.5gb ethernet adapter by replacing gigabit ethernet, I felt that audio quality much improved.
It could be the the reason for this that 2.5gb controllers handling common mode noise better than gigabit ethernet controllers. Please google it if you curious about common mode noise and how could it affect audio qualify.
Anyway I bought an 10gb ethernet adapter using aQuantia AQtion NIC. (AQC107)
But I couldn’t make it to work with volumio.
If you provide support for that ethernet controller, I could test the audio quality with 10gb ethernet adapter.
Thanks.
