Apple lossless as a source

You can airplay apple music from your iPhone or iPad to a streamer that supports airplay. It’s a better option than Bluetooth. Honestly in that system you are unlikely to suffer a significant sonic degradation. If you want something better you woukd have to get a streamer with a built in DAC and subscribe to Qobuz or Tidal. 
A used Lumin D2 is a decent option in addition to what was already recommended above. I believe it also supports airplay but I would get Qobuz or Tidal and leave Apple Music for the car or a gym (Qobuz and Tidal also have apps and can replace Apple Music altogether).

I stream Apple Music from a Samsung tablet via Chromecast to my Cambridge Audio streamer.  The High Resolution tracks that Apple offers sound great this way.  If I use an Apple device, such as my iPhone, it doesn’t offer Chromecast so I have use AirPlay, which is better than Bluetooth, but Chromecast is preferred 

This whole thing reminds me of 4k tv.  No normal person can get 4k all the way from the service to the tv without a doctorate in gadgetology.  Luckily I'm semi retired and have time for all this.

I got a subscription to Qobuz and will try that out.  Of course, when I tried to bring over a playlist from apple I had to go through some third-party app that wanted me to subscribe to the premium version or it wouldn't move more that 200 songs. :-(  Rebuilding my 650 song playlist will be a project.

Qobuz should build a converter from other services in to make it easier to switch.

I'd prefer to keep the streamer and DAC/preamp separate.  I think the streamer will be obsolete long before the DAC.  Preamps never die.

There’s a Octo dac8 Stereo that was highly praised in a stereophile review. You can add streaming as an option to it. My guess is you will have a network renderer in the dac8 that will allow you to use Mconnect to stream qobuz. I think the paid version of mconnect is about $6 or so if the free version isn’t good enough after you try it.
Throwing this out as option as that gives you a very decent DAC and ability to stream for under $1500 new. I haven’t heard the dac8 and am simply going by what I read in the review. I’m sure there are some on these forums that can chime in.
Running iPad into your amp is definitely an option but it’s just neither convenient nor good.

Nothing like asking one day for help with Apple, and then announcing the next day that they have switched to Qobuz.  I think I will wait a few days before I answer the next such query
