i have an older iPad 3 which I would like to get another year out of if possible. I would like to play MP3 files from iTunes and also Spotify as well. Wired from the headphone jack of the iPad, the music sounds quite good but I am looking for a wireless device with the best sound quality. I looked into the Arcam rPlay but I cannot afford anything that expensive right now. I am also a bit weary of buying used because I don't think the build quality on these units is anything to write home about. I also read about the Sonos connect which got mediocre reviews on sound quality so right now I'm lost in the woods about this.
