I have Libratone speakers [0]. They do all of that. (Alexa is integrated; off by default should you not want it.) And they sound fabulous. Streaming is available via Airplay and Bluetooth. The Libratone also contains a 10-hour battery, so you can take it wherever you want – stream from your phone in the park, if you like. Oh, and it doesn't leave white marks on wood surfaces [1].
