I don't know but the audiophile community is pushing network streamers. I would consider moving to streaming, but not if there's a drop in sound quality.
All about streaming
I'm an audiophile who's been through album, cd, and mp3 formats. I currently have a laptop hardwired via usb to my audio system and usually listen to mp3's purchased through Itunes. I recently subscribed to Spotify premium which is connected to my wifi network. I've noticed that when listening to the same material, the mp3's sound much better than the Spotify version. Would I get better sound from streaming via ethernet?
