One box solution

I would suggest considering the Aurender AP20 as an all in one solution. I am very impressed with mine. In another room I have a pass labs X350 amp so we may have somewhat similar taste in sound. List price on the AP20 is $22k but you could probably get one pretty close, but slightly over, your budget. On another note, I have 12 zones of NAD distributed around my house and am happy with it for that purpose (in cieling speakers - casual listening). I was excited to hear the M10 but just didn’t like it very much at the store demo. Lot’s of different variables go into this stuff as we all know but wanted to share my experience in case it is of any value to you. Good luck with the move. 

Spend money on the speakers like Wilson Tune Tots. For the all in one NAIM is a good choice.

Check out the AVM CS8.3, a true all-in-one Class D with a tube input stage. It has a DAC, streamer, and built-in CD player.

+1 for Aurender AP20

I had an A20 for a while and it was a fantastic unit.  Aurender's build quality is top notch as well.  I did a quick search and there are not any on the used market now.  It also has a headphone option....that would most likely keep you happy for many years to come.

Actually I would recommend receiver with streaming, good headphone amp and pair of high end headphones. This way you can even listen at night and control system from an iPad or another tablet. Using tablet as a central device will also allow you to watch movies or youtube, etc.

Say, $4K headphones like Meze Elite or Focal Utopia, Pass or Denafrips headphone amp at around $2-3K and, streamer and active speakers like Dynaudio.
