I don't know if it's a small manufacturer, but you really can't go wrong with Harbeth. I have the SHL5+ and they are stunning. My room is too small for the 40.2s, but they are even more impressive (in the right room).
As an aside, I recently added the SOtM Duo bridge and word clock to my system powered by an Illuminati DC supply. I would not have thought the Harbeths could get any more detailed, but what an improvement!
