I’m in a similar boat and researching speakers with great presence at low volumes..All my reading has yielded the single most important ingredient needed is high efficiency...I am looking at Spatial Audio,Reference 3A and the Silverline Audio Prelude Plus,check them out...
Another route is to put together a nice headphone system...A nice little tube amp and circumaural open back cans(HiFiMan,Audeze or Sennheiser's)will put a big smile in your ears and still allow audio connection with the outside environment,ie:crying baby etc..
