Yes, this works if you connect the following device: SONOS CONNECT (Weiss) to the line out (tape out). The whole thing is not cheap and depending on the distance between the stereo system and the bedroom you will need a boost SONOS BOOST.
I would have thought that the SONOS one could be connected directly to the amplifier. Too bad, it's not worth spending so much money on such a solution. :/
