After using Picoreplayer for the past week I have now returned to Volumio to try out it's Airplay feature, all I can say is that it's working great. Spotify free playing on my main system via Airplay using my ipad. Something I could never do using the Touch or via Volumio which needs a premium account, also works great with the Radio Paradise app. I can also play songs from my NAS via ipeng's built in playback feature, but only upto 24 bit/48 kHz sound quality, I need to switch Airplay off and revert to Volumio for higher res files.
