Upping a Bluesound would be moving to an Aurender.
Unfortunately, Aurender only offers Qobuz and Tidal, so if you want the variety Bluesound offers, your going to have to stay with them.
That being said, upgrade to a high quality DAC- like Ayre Codex or Schiit Gungnir or Yggy ( I mention these only because they outperform from their price points).
I have listened to both Aurender and Bluesound with the Codex and can say it is a very good match for the money.
