For less than 200 EUR, I have found no better sounding box with these dimensions - and I have many sample belongs! The Airplay setup through the app is "foolproof" and when you know that you can be switched on briefly pressing the rear button playback in the dock, and everything works out right away ... As always with higher quality speakers should be best to feed the Z2 with uncompressed material (-> Apple Lossless MP3 instead), because it applies the principle of "garbage in -> garbage out". Then you will be rewarded with crystal-clear highs, balanced midrange and deep bass. Excellent! I'm going to order me another 2-3 more Z2S for the apartment ...
