Surely it is not suitable for parties or similar purposes, is expected in the very loud music with rich bass. For normal street in living or dining room, but highly recommended.
The reviews, there AirPlay dropouts etc., I can not understand. Probably should be the ones your wireless network simply time to revise. It is quite clear that the streaming only works properly if both the Fidelio, as well as the iPhone (or similar) on good wireless reception with no "dead spots" feature. So possibly even change the location of the wireless router and replace this with a device with external antennas, then it will come smoothly.
