@soix Everything is going to sound different, better or worse. Different CD players are going to sound different but one thing I can honestly say is that a computer, NUC or Raspberry POS is never going to sound as good as a quality dedicated storage/streamer.
From experience I really tried to get the computer thing to work but it just doesn't.
If you want real sound you have to get a dedicated streamer with everything that goes with it, but first rip your CDs and see what sound you're getting from a quality storage device not a NAS or USB/HDD.
