Digital music questions

There are endless options, but as others have said you will have a much better experience moving on from your PC, I started with Bluesound  and now use a DCS Bartok. The point I would make is that the Bartok is really good in my opinion but also really expensive. While it's much better than the Bluesound, as you would expect given the price difference, that doesn't mean the Bluesound is bad, in fact, I always thought it's a great bargain for what you get. Decent streamer and DAC and very easy to use for not a ton of money. 
 

not a bad way to start and miles better than PC. From there, there are many, many choices at every price point and I suspect you'll be on the upgrade path at some point but nothing wrong with an affordable start like the Bluesound- you'll appreciate the improvement. Would also highly recommend going with Qobuz or Tidal- I think you'll find that an appreciable improvement for the dollars invested. I prefer Qobuz but both are good 

You may want to check out a previously owned Lumin to get started along with a trial to Quboz.  You won't be disappointed and will never look back except to question why you didn't do this sooner.

Let us know how you make out.

OP, like many have said, just start with a Bluenode. You can upgrade later as your budget allows and your taste for more digital performance increases. 
 

Regarding Apple Music, supposedly, Hifi Rose supports high res Apple Music natively, up to 96/24. I have not tried this myself, so hence the supposedly.

   You ask a lot of really great questions.

   I was using Qobuz for a couple of years.  My wife really wanted to use Apple Music, and like you, I didn’t feel like paying for an extra subscription.  I use the streaming service primarily to sample new recordings, and then if I really like something I buy the CD or SACD, and then either play the disc or burn it to my NAS and play it from the streamer.

   I play Apple Music on my Cambridge Audio CXN 60 streamer.  If I use an Android device I use Chromecast.  If I am using my iPad then it’s AirPlay.  Chromecast sounds better.  The CXN60 comes with a DAC,but I only use it as a streamer, running it into my Bryston DAC3.  Yes, I have paid for DAC that I am not using, although the included DAC isn’t bad and I suppose will be a backup DAC for my entire system if something happens to the Bryston.  It should be possible to get streamers without DAC that offer Chromecast and AirPlay.

   Like you, for years I streamed from a MacBook, reasoning that it shouldn’t sound different than a dedicated streamer.  As others have noted here, even budget equipment such as Bluesound or my CA ($1100) easily best the sound of computer audio.  For me it as the lack of grain andquieter backgrounds, and also the joys of not hearing my music mixed in with extraneous computer sounds.  I also prefer an audio component to look like an audio component and not a PC

I use a Bluesound Node connected via coax to the DAC1 in my McIntosh MAC7200. Bluesound's coax connection bypasses it's internal DAC enabling me to use the MAC's internal DAC and features. It sounds great.

The Bluesound interface / control is via my iPhone and is very stable and easy to use. My Bluesound node is connected via Ethernet to my router.

My paid streaming services are Amazon Prime and SiriusXM. Both are native to the Bluesound, so I'm not streaming thru my phone. The Bluesound also has iHeart, TuneIn, and others that don't require a subscription.

My next big upgrades will be a Mac DA2 and an MS500 streamer.

Your C2700 uses Mac's top of the line DA2 - enjoy!
