Bluetooth hifi

I'm not too sure which group this post should go, so I'm hoping I'll get
some answers here.

At the Moment I have a rather old ,15 years, Denon DRA-F101 and a
DCD-F101, and I would like to replace it with something more modern!

By that I mean something with either bluetooth or wireless, as I have a
pair of wireless, not bluetooth, speakers. These are used to play
streamed music from my NAS box to my Android tablet in another room.
I was hoping that there would be a wireless HiFi I could get, but after
speaking to someone at Richer Sounds there are no wireless cd players
only bluetooth.

I have been looking at getting the Sonos Play 1 wireless speakers, but
can't work out how I could use them.
It would seem that the said wireless speakers can only be used with a
wireless device like laptop or tablet.

Are there any can do's and cannot do's with what I want
