I use to own Magnepan IIIa's with the true ribbon tweeter and there are very few speakers that can produce the quickness and imaging as the Magnepans and so my speaker hunt was filled with disappointment.
The SoundLabs will produce more of what you were experiencing. They were too large for me in my small room.
But my quest stopped with the Wilson's because then I had that pinpoint imaging BUT with Dyamics and Volumn which I hadn't been able to get otherwise. The Sophia's would be an excellent match with tubes, as I heard them on a stereo VTL150 amp and my friend powers them with an ARC VS55i (which is not enough power for bass control but still amazingly transparent). I ended up blowing my budget and buying WP7's (now I drive a cheap Honda as a sacrifice for my stereo).
Wilson require time to setup and careful component matching to get that ultimate synergy (Going with tubes will help your quest)
Enjoy the hunt.
