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.
