I got me a good 2 months ago a bridge, a 10er and a 20er Box buy and find the sound very well. The design is very convincing. Granted, the app is not really the yellow of the egg, which is but hopefully also. What I can not understand the problems in setting up the system, many of which are described here. The setup was very easy, the connection to the devices via Bluetooth (Mac, iPhone, iPad, etc.) to work smoothly and also the transfer of the boxes to each other works perfectly with me. I think that a lot of problems that are described herein are not related to the boxes, but rather with the wifi setup altogether. I very much hope that the Harman Kardon app yet nachbessert strong, because there is still a lot to do actually. At the moment I can live without that, however, because I either via Bluetooth or Airplay streame (involvement of my Apple Airport via the bridge) and follow all apps like Google Music, Spotify can use etc..
