Two years ago, I demoed 3 of the 4 brands that you are considering. I have not heard KEF speakers since the late 80's. If you end up leaning towards Revel, I suggest the following:
1) Read the review of the F206 in SoundStage! HiFi (9/14) that was written by Douglas Schneider, who is a frequent contributor on this forum.
2) Also, read the review of the F208 in Home Theater Review (11/13) that was written by Brent Butterworth. As much as he liked the F208, he ended up buying the F206 instead and pairing it with a subwoofer(s).
Good luck in your search, and let us know what you end up buying!
