Would Kef LS50 work? I have not heard them but they seem to get high praise on the net
A friend brought his up for a weekend and compared to my GR-Research N-2X kit speaker. I liked the GR product better, better instrument placement detail.
Now, AJ in Fl over on another audio site makes a damn fine speaker using a cheaper version of the LS50 driver. KEF put him out of business, but you might contact him anyway.
Other than that, I've heard a little Revel bookshelf that were really impressive. Detail, space, soundstage... but they weren't cheap. I'll find the model and get back.
