I think you will find the biggest difference will be moving from Spotify to Qobuz or Tidal. In my experience the CD quality, and higher, of these services will yield a far bigger improvement to the sound than improving the streamer/DAC.
At 320kbs Spotify is a long way below CD quality. Playing Spotify through a better streamer/DAC will make a small difference. Playing Qobuz or Tidal through the Bluesound will make a massive difference.
