This group of speakers seems to have quite a variety in sound. To my ears, the Revels & Wilsons are similar in signature, with the Sophias being more balanced if driven by high power tubes(e.g. Mac monos). When I saw other Talons at CES, they also were mated w/big tube monoblocks(i.e. Joules). Never heard the Raven. The Divas are warmer balanced, a tad on the polite side, but I like these better than the others you've listed.
I'm biased as I own them, but I think Merlin VSM-MX would be a perfect fit. They match the description of what you are looking for, and they are tube friendly, with a small footprint that works well in many smallish rooms. Granted they do like some room behind them, but no more so than all the others you mention. If you call Bobby @ Merlin, he could advise you as to how well the KR's would work w/the VSMs.
If keeping the amps remains a high priority, Coincident offers many models that are good with lower powered tubes. One note of caution, they vary widely from model to model, not much of a house sound.
