Which monitor speaker to choose??

Lots of good recommendations. For imaging I'll throw in the Joseph Audio RM7XL or Silverline SR17 (or SR17.5 even better if you can find them) as well. Not sure how much detailed and dynamic true bass you're going to get from monitors, but adding a sub or two down the road would certainly take care of that. Best of luck.

I received my vapor breeze a few weeks ago and must say that they are amazing for the price. The soundstage and imaging are wide, deep, and airy. Voices are very realistic. They are detailed but not at the ultimate expense of smoothness. The bass does not go to the lowest extremes, but they go low enough for enjoyment in my 12x13 room. It is also fast and detailed. I like the vapors so much that I am considering an upgrade to their cirrus, which uses the same raal tweeter but much better woofers. I hope to hear improved bass, refinement and coherency from the cirrus. But for the money, I don't think any speaker can come close in sound, build or parts quality. I've tried some of the speakers that others have mentioned and the breeze are in a different class

You have to give the Lipinski L707's a listen. I have them in a 12x 14 room and they also worked in a 24x34 room with a sub. I have an all tube system, but I just got a Linn Classik for times that I only want to listen for an hour or two. They sound great hooked up to it,( I've owned all kinds of Klipsch speakers, Polk Audio, Linn Katans, Ninkas, Majik 140's and others,) but the Lipinski's have them all beat. You'd have to spend well over 10K to beat them. Remember, the best speakers in the world will only sound as good as what you feed them, no matter what anyone says. Otherwise, you could hook up any cheap high powered receiver to them, and they'd sound great. Good luck.

I owned the Sonus Faber Concertino Domus... very, very nice sound (esp. on tubes). I would take these over the newer SF monitors.

Might be worth considering Triangle Comete monitors which offer very good value I would say before sinking more cash into monitors.

Being familiar with Rebbis quest for the ultimate sound, Reference 3A is another line with some unique and valuable design considerations that has come to my attention recently that I would give a look at for potential value.
