Best Late Night Low Volume Speaker

My Reference 3A de Capos sound pretty good low volume, nice dynamics.

My Harbeth 40.1's are the best I've heard at low to moderate volumes.

Onix Strata Mini's with Cayin A88-T integrated tube amp and Jolida 100A CD player

My feeling is that this is best achieved by reasonably efficienct speakers and low wattage amps. I have Coincident Super Eclipse (94db/w/m) and 300B-based SETs and listen a lot at low volumes - I'm an apartment dweller.

Obviously you have to avoid speakers that take a bit of welly to get up and go.
