Triangle Titus XS (<$400 used) monitors are perhaps the most articulate speakers I have heard at low volume. I would compare these to Dynaudio monitors that I own that are more like Totem and excel at higher volumes. They are also about 90db efficient and are known to mate well with tube amps.
Magneplanars are another good choice but can be harder to position optimally in tight quarters.
