Need to get off of bluetooth.... looking for a wifi streamer for my budget

Wow, this is so painful. It looks like no one supports Apple music. All my playlists are on Apple. That’s what makes me stuck on Apple. Otherwise I’d go somewhere else.

Sometimes in life one must face the consequences of their actions. 
Time to punt sooner rather than later.
I’ve only had Qobuz so cannot speak to the merits of Tidal. 
With Qobuz there are so many already made playlists I’ve never created a true playlist of my own. The one I did create was due to need not want. 

Punt. 

You can export an Apple playlist and then import it into Roon and/or BluOS.  Not sure how effective it is and you would still have to get a subscription to Tidal or Qobuz as well as to Roon, if you want to go that route (which would maybe take you past your ~$500 budget).  Or just stay with Bluesound, and BluOS.

What if I could stretch the budget to 1200 for a used streamer? Would Rose be a good brand? Or is there something better to look for in that range?

You might look into the iFi Zen Stream. It retails at US $399 and has a 30-day return period (in the US). I have not tried one, but I've built a couple of RaspberryPi-based streamers and though they were very good to excellent in a revealing system. Anyway IMO a lot of streamer performance depends on the quality of the downstream DAC; how good it is, and how well it rejects jitter, noise, etc.
