I just bought Beosound 8. It has great sound, especially for the higher bit rate music. I do have a couple of observations though:
1) iPad 2 wobbles quite badly - it is too thin for the docking mechanism. I write to Customer Service and the referred me back to my dealer but he has the same problem and at least another customer complained. I don't believe this is iPad tested/ready.
2) The B&O app in the AppStore is, well, amateur. I did buy it for the 12 Euro since I have a great iPad tuner app and I can also stream stations from my mac iTunes.
The major disappointment, though, is that with the unstable docking situation I would not want to wall-mount - the iPad 2 would fall out of the vertical position in no time.
