I am looking to replace my cd player (Arcam CD72)with a network player primarily to rip my old cd's,to utilise internet radio and for spotify/i tunes. My separates system (Arcam CD 72, Marantz PM 6004 Amp, Project Carbon turntable) and router is downstairs whilst my desktop is way away up stairs. I dont really want to have a wired connection between the network player and desktop, so other than wirelessly is there another option to connect to my desktop?. I have looked at the likes of the marantz na7004 and pioneer n50 as well as cocktail audio x10?. It would be an advantage due to space to have a hard drive combined the network player (ie cocktail audio) over purchasing a seperate NAS. Furthermore would any network player i mentioned be improved with the inclusion of a DAC?
