Since I have this Speaker, my surround system is hardly used. Why? It is so beautifully simple. Thanks Spotify has almost all the music available. There is no need nasch CD's Search or connect your computer to the system. The Speaker will once brought in-Fi. With a special App you can connect the Speaker or select them individually. So you have a system for the whole apartment on a single click. In the Spotify app one can select the desired sound, chasing playback source the Speaker. Even there you go. You can also completely close the app, the Speaker take the stream and play until the stream ends.
Only a power cable needs to be connected, the rest goes via tablet. So easy it can be.
The sound from large speaker SW750M my opinion is surprisingly good and definitely enough. Therefore, I have the plant only rarely.
Cons: The great strength - the connection to Spotify - is also the weakness. One is to have forced a Spotify Premium account. I have, but who knows how long? Without as it gets. You can connect any other source. I Solte me say goodbye to Spotify, I can no longer use the boxes.
