I have owned the Aerial 9s and had to sell them because of a move to a smaller room. They just did not work in that room which was 13x15x8. I had the model 6 before I traded up to the 9s and they would work in your room. The model 6 are actually less efficient than the 9s or 7t though. You would need to change to a high power ss amp for any of these speakers unfortunately.
I personally did not like the dealer demo of the Dali 400 I heard. I also don't think Dali speakers are designed with tube amps in mind.
Though I have not heard Coincident speakers I believe they are a good match for tubes. I think your best bet is to go listen to some if you can.
Do you have a Tannoy dealer around? I have heard the Glenaire sound quite good in a small room.
