I use a marantz mcr 603 in my kitchen. The sound through kef cq130 ceiling speakers is great far better than I expected. However the online options are very slow even though I use a wired connection and there's no Spotify. Hopefully the 610 keeps the sound quality and improves on the networking.
Thanks for advice. I can now access via the receiver but couldn't get the iPhone app to work. Still better than before and I now tend to use the tv instead. A lot of my files are aiff so I have to convert to mp3 to solve compatibility issues on other devices.
