Wow - that's quite the nice package you are looking at! The Marantz looks like a nice unit, but my suggestion would (*at this time) a Bluesound Node 2i:
The Bluesound NODE unlocks the world of hi-res music streaming and multi-room audio to create a modern addition to existing hi-fi systems or your favorite set of powered speakers.

It is a DAC, Pre Amp, Wireless Streamer with a great, VERY simple OS, accessible from a laptop, phone or tablet. The OS recognizes Tidal, Qobuz and Amazon (among many others) and the files on your hard drive. Also, it sounds pretty darn good - do some reading up on it (lots of reviews via Google).
I have one and it is one of the best purchases I've made in a very long time. I also purchased Roon and I cannot say enough good things about that progam - again, Google it.
* I said "at this time" because it is my feeling (just a feeling, mind you) that your potential system could benefit from a dedicated pre amp - something to look at further down the line. Have fun!
