I have 2014 NDX, don’t stream but do play a lot of high res files
the best £500 I have spent was getting a local company to fit cable from my router (front of house) to my music room (rear) direct connection from switch to ethernet and then through garage, through the walls and into my music room - get 100mbs at the NDX never an issue since fitting no drop outs
the cost in ££ vs music and moreover the issues no contest
