With my limited knowledge, any streamer send the "music" in digital format (Wifi or BT) and the inbuilt "receiver" of the speaker would take it, decode it and convert to analog for the amp to amplify it with it's in-built DAC. So the DAC inside the speaker is a must.

@mbhangui ) am i correct with the above statement?
With the Arylic you can connect to an amp if you wish to apart from streaming to the speaker. In the thread I posted above a FM with Arylic has described how he is doing.
