In my experience, the best for low volume listening are slightly-bright speakers that have very good analytical power and sensitivity. The amps don't matter as much as the speakers do so you need to tackle the speaker choice first. Triangles are a great candidate. I have never heard any speakers sound as good as they do at low volumes.
Tube amps are a good choice as well. I find that SS amps' lose bass at low volumes whereas tube amps don't. The Fletcher Muson curve will tell you that human hearing needs extra bass at low volume to get a linear response. So keep that in mind.
