I have a pair of B+W 602S 3s powered by Arcam alpha8r amp. Still sounds great so dont want to ditch. These days though out of convenience mostly streaming spotify premium re headphone cable from smartphone to aux socket. So looking to upgrade with a dedicated streamer with DAC (or possible amp/streamer combo as i have some functionality issues with the Arcam) and connect through the amp aux. I would also like to be able to add some wireless active speakers in other rooms which I hope would be able to communicate with the streamer wirelessly (bluetooth probably). I am very new to all this so have no idea whether this would work or whether there would be synch issues between the wired and wireless speakers when playing the same music. There seems lots of systems out there bluesound, sonus, yamaha etc and it looks like I have to stay with one manufacturer's ecosystem (streamer and wireless speakers). I would prefer not to as there would be more choice. Any advise appreciated.
