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.
