Looking for streamer

piCore players do Deezer through Squeezlite. Like this one, includes directions to do it:

And of course the infamous BluSound 2i.

I was looking at Stack Audio link II as well

The Link Ii has certainly evolved. If his current player indeed supports Squeezlite it should work. Email Theo and tell him your plans. It's in the same $ range as the Mano. See if Theo can send you instructions for running Deezer. I know that Rob & Jos do at Magna.
