Now I have the ZP 120 gave myself for my hobby room. It runs at Canton standing speakers that are well designed for twice the amplifier power. Here again the sound convinced. Powerful bass, clear highs, and excellent spatiality. The full digital amplifier really brings everything out of the boxes which is possible.
On the subject of ease of installation and operation, including regular updates by Sonos has been written in the other reviews already enough. I can only agree. This includes the ease of use of Napster or even the countless internet radio stations. Throughout Germany can be most radio stations in good (albeit not WAVE) listening quality.
In my opinion there is no reason to spend more money for a streaming player. Also more than 1,000, - expensive players do not sound better after my own experience!
