Quality streaming for newbie

@griff69 well the LUMIN U1 Mini is a pure streamer at USD $2000. Or as audiotroy mentioned there is the D2 at USD $2300 which has a built-in DAC for analog outputs. So if the D2's DAC stage sounds good to you, you can get both a streamer and DAC within your price range.

And you could always use a different DAC later while still benefiting from the D2's streaming software and hardware by using its digital outputs.

If you want to use AirPlay (for Apple Music) then there are dozens of products to choose from as almost every mainstream consumer brand has released products with AirPlay support. It really comes down to the user experience and differences in sound quality.

If you can play around with the apps or watch online videos of the different user interfaces, that might help. Although if your only intent is to use AirPlay that may not be an issue.

I’m using a PS Audio PerfectWave DAC MK2 with a Mac Mini and they sound heavenly together for streaming purposes.

Are we talking Naim ND555 ($33k) or a MAC Mini and a budget DAC, what do you mean by quality? 

If read the OP correctly he or she wants to upgrade their sound with a DAC, still play CDs and investigate streaming.  What I am unclear about is whether the OP currently has a useable CD player.  If so, and if it has digital outs, then it can be used as a transport, and then 
the OP only needs a DAC and a streamer.
  If the OP needs the whole shebang—CD replay, DAC, streamer, CD ripper—examine Cocktail Audio.  They make a range of units within the budget and I haven’t heard them but they get generally high marks.  Some come with amplification.
  If the OP already has a CDP and a ripper, then within budget could either purchase a pure DAC with a streamer separate or an all in one.  Investigate DACs from Benchmark, Schiit, Mytek, and consider
adding a streamer such as the Bluesound Node.  Companies such as Auralic and Aureender are now issuing streamer DACs in the budget.
  If the OP isn’t fully convinced about streaming they could dip their toe in the water with Google Chrome Cast, which is inexpensive and well liked by many people.  Coupled with a good DAC, it might satisfy their needs for a long time, and the OP can always upgrade later.
