I have used a Plinius 9200 with the Carolina Audio single driver (medium efficiency Jordan JX92 drivers)- very holographic, nice combination. Jordan based single driver speakers (Carolina Audio, Konus, others?) are easy to place in any medium or small room, amazing imaging/soundstaging, surprisingly accurate and coherent bass. These are the only single driver speaker I am aware of that match well with solid state.
You might also consider a system with digital room and speaker correction (DEQX, Tact). I have been using a DEQX preamp on multi-driver speakers, resulting in coherency and a holographic sound similar to single driver speakers. NHT has just introduced a DEQX-based system for about 5K that also includes the amplifiers. A set-up like that might get you a lot closer to what you are looking for than another overpriced pretty box.
